Went Intrepid today -- The events/0 problems is gone. It was perhaps a the relationship between the version nm-manager in 8.04 and rt61pci driver in 2.6.27-4.

linux-image-2.6.27-4-generic and rt61pci on my machine has serious problems with resume from suspend. events/0 pegs the cpu at 100% and keyboard becomes unresponsive. It happens on about 80% of time, the other 20% of time it will resume fine - but removing the network card and reinserting it will cause the issue after the case of a initial successful resume. This problem does not happen with 2.6.24-19-generic and version 2.1.4 of the rt61pci in linux-backports-modules. -- [rt61] Lockups running Feisty on x86-64 https://bugs.launchpad.net/bugs/90243 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I have a level one wpc-301 v4 that is affected by rt61pci lockup issue in hardy using 2.6.24-19-generic and version 2.0.10 of the rt61pci module. I slapped on linux-backports-modules which seemed to resolve the issue with the hard lockups, but activity light on the card stayed lit regardless of activity. I have now installed linux-image-2.6.27-4-generic_2.6.27-4.6_i386, and so far all seems good, as it has not locked up yet and problem with activity light is gone. -- [rt61] Lockups running Feisty on x86-64 https://bugs.launchpad.net/bugs/90243 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test: 1) If you are comfortable installing packages on your own, the linux- image-2.6.27-* package is currently available for you to install and test. --or-- 2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD. Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback. ** Tags added: cft-2.6.27 -- [rt61] Lockups running Feisty on x86-64 https://bugs.launchpad.net/bugs/90243 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 90243] Re: [rt61] Lockups running Feisty on x86-64
Rather disappointing that Feisty went live with this bugged driver from SerialMonkey I had gone at length in Edgy to get the rt61 running with WEP, by removing the rt61pci module and downloading and compiling the rt61 driver from ralinktech.com, finally with success. Now after the upgrade to Feisty everything was broken again: the distribution ships with a rt61 (same name to add to the confusion), which is not configured to my WEP needs, and connects to my neighbors unprotected router. After endless ifconfigs, ifups/downs, /etc/netwrok/interfaces, iwconfigs etc, the system got completely instable with the afore mentioned deadlock. Reverting back to ralinktech.com learns thereafter that now I also cannot compile the available driver anymore, due to kernel changes for net_device. Cute. Many hours later I managed to got it to compile without errors and all is working. That's all thanks to having a multiboot system, where I still was able to get to some files and network ... I was a big fan of Ubuntu, but my enthusiasm has diminished.

[Bug 90243] Re: [rt61] Lockups running Feisty on x86-64
I resolved my problem with the rt61 driver by switching to the 386 kernel and the system is rock-solid again. As the 386 Kernel isn't build with CONFIG_SMP this is just a work-around for people using old cpu's wich don't need the SMP feature. Of course this is not a solution to the problem as the SMP feature is important for the future, but for me it's the only possibillity that I've found, which let's me work with this adapter. The status of this bug is still needs info, but I think that we've gathered enough information on this issue. I know it's very late, but please throw this driver out of feisty and include the one from the rt2x00 project, if it realy works well. Also if that one isn't stable enough as the developers say, it should be better than this one, at least for the generic version of the kernel fof feisty. Cars using rt61 aren't that exotic at all and I think it would be very important to finish this porblem before the release. -- [rt61] Lockups running Feisty on x86-64 https://bugs.launchpad.net/bugs/90243 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [EMAIL PROTECTED] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 90243] Re: [rt61] Lockups running Feisty on x86-64
Looking at the traceback that John Clemens just posted -- it looks pretty obviously like another variation of the same class of deadlock that I described before: - BeaconTimeout() ran from a timer, and calls into MlmeHandler() - MlmeHandler() runs the table-based state machine - The state machine calls MlmeJoinReqAction() - Right at the top of the function, MlmeJoinReqAction() does del_timer_sync(pAd-MlmeAux.BeaconTimer); - But we're running from the BecaonTimer callback already and voila, we have another wait for timer to finish from within timer callback deadlock. Looking at the rt61 driver source, I really feel it was a mistake to merge this into the Ubuntu kernel in the first place. I realize that there are probably some people who are using the rt61 driver without lock ups, but at this point I don't think feisty should ship with rt61 enabled by default. I think the reason this bug is having a more severe impact now is that all kernels are built with CONFIG_SMP now, so del_timer_sync() is never converted to del_timer(). So another possible fix would be to enable the code in rtmp.h that does: #undef del_timer_sync #define del_timer_sync(x) del_timer(x) that would probably convert this easily-triggered deadlock into much rarer strange crashes on SMP systems.

This is still a problem as of 4/9/2007 (kernel 2.6.20-14). I just
removed the rt61 card from my system for now, but if it's at all
possible at this late date, please do -not- ship feisty with this bug.
It's very hard to diagnose ('Everything just stops, except mouse
movement!'), and rt61 cards aren't all that uncommon.
May I ask what exactly 'needs info' about this bug?
In my logs I found the following, but the machine ran for a while after
this and then locked up hours later. When it actually locks, there are
no messages saved in the logs, and I don't have a serial console
available right now. Removing the rt61 card from my system has restored
stability.

[Bug 90243] Re: [rt61] Lockups running Feisty on x86-64
OK, I managed to get a traceback of the soft lockup on my system, but unfortunately I screwed up and it didn't get captured like I thought it was. So I don't have the traceback, and I didn't read it that closely before I rebooted, since I thought I had it saved to study later. However, I did look at it enough to get the idea that some MlmeXXX function was calling del_timer_sync() from a timer callback (which is of course an instant deadlock). And indeed, the first del_timer_sync() call I check shows the following problem. MlmeAssocReqAction() (which is called from the STATE_MACHINE obfuscation) does del_timer_sync(pAd-MlmeAux.AssocTimer); and AssocTimer runs AssocTimeout(), which calls MlmeHandler(), which runs the STATE_MACHINE crap. So the AssocTimer callback can deadlock easily. Based on this, rt61 seems utterly broken by design and prone to deadlocking if anything times out. Aside from this deadlock problem, the source is bloated and unreadable, so I think the best thing to do would be to throw it away once and for all. The rt61pci driver seems a lot saner to me, and indeed a complete rewrite like that seems to be the only way to salvage this driver. I don't know what the problems with rt61pci are, but I don't see how rt61pci could be worse than rt61. If I get a chance I may try (out of morbid curiousity) to get the exact traceback that's deadlocking my system, but I don't have any hope that the issue will be fixable without a driver rewrite. -- [rt61] Lockups running Feisty on x86-64 https://launchpad.net/bugs/90243 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 90243] Re: [rt61] Lockups running Feisty on x86-64
I also can confirm this problem. A Ralink pci card 00:09.0 Network controller: RaLink RT2561/RT61 802.11g PCI is driven by the rt61 driver. I have a 32bit single core system, so I don't think that the problem is SMP related. Same problems here: The system freezes completly from one second to another, sometimes after a few seconds, sometimes after some hours. Like Frode Solheim I also got the message soft lockup on cpu#0 as the system freezed without X loaded. -- [rt61] Lockups running Feisty on x86-64 https://launchpad.net/bugs/90243 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 90243] Re: [rt61] Lockups running Feisty on x86-64
I can confirm lockups with rt61 driver loaded. I have a ralink card in a computer: 04:08.0 Network controller: RaLink RT2561/RT61 802.11g PCI When the rt61 driver is loaded the computer locks up sometimes during boot, sometimes after a few minutes of usage, and even sometimes after a couple of hours. When using a graphical environment, I experience the same symptoms as the poster. The keyboard hangs first, mouse still works a couple of seconds, soon everything is locked. I once got the following message in a virtual console just before the hang: soft lockup on cpu#0 I have a dual core Athlon X2 processor (SMP-related problem??) Without the rt61 module loaded, the system is completely stable. I have now deleted the ko file to ensure it doesn't get loaded by accident until the problem is resolved. -- [rt61] Lockups running Feisty on x86-64 https://launchpad.net/bugs/90243 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 90243] Re: [rt61] Lockups running Feisty on x86-64
Thanks Kyle, but it seems that rebuilding the kernel is a little harder, or perhaps the linux-source package is broken. I had tried basically your suggestion before and failed, and I just tried again. I installed linux-source-2.6.20 and unpacked /usr/src/linux- source-2.6.20.tar.bz2, and then in the resulting directory I ran dpkg- buildpackage -rfakeroot as you suggested. That did some stuff but eventually died with: == making target clean [new prereqs: stamp-clean]== dpkg-source -b linux-source-2.6.20 dpkg-parsechangelog: error: cannot open ./linux-source-2.6.20/debian/changelog to find format: No such file or directory dpkg-source: error: syntax error in parsed version of changelog at line 0: empty file the command fakeroot debian/rules binary-debs flavours=generic dies with == making target .config [new prereqs: Makefile]== test -f .config || test ! -f .config.save || \ cp -pf .config.save .config test -f .config || test ! -f ./debian/Config/config || \ cp -pf ./debian/Config/config .config test -f .config || test ! -f ./debian/config || \ cp -pf ./debian/config .config test -f .config || (echo *** Need a config file .config false) == making .config because of Makefile == test -f .config || test ! -f .config.save || \ cp -pf .config.save .config test -f .config || test ! -f .config || \ cp -pf .config .config test -f .config || test ! -f ./debian/config || \ cp -pf ./debian/config .config test -f .config || (echo *** Need a config file .config false) make: *** No rule to make target `binary-debs'.
