Some more data points: * I've tested extensively with the i386 version now (though I haven't seen any reports of it there). I ran 3 alt i386 installs with LVM+crypto in virtualbox at the same time on a 4-core box without getting any hangs. * I ran both the i386 and amd64 versions in qemu Without the kvm HW acceleration, with no hangs. * I ran two 64 bit installs /w LVM+crypto at the same time, one allocated 384MB RAM and one allocated 2GB, both with an 8GB disk. They both seemed to stop at the same time and very frequently, every 3-4% of progress. I killed the 2GB RAM version and let the smaller one continue -- and it would stop less often every 8-10% perhaps.

Just a thought - is it trying to load a screensaver / blank screen, but not actually changing the screen - therefore the moving of the mouse / pressing a key cancels the failing attempt and continues the installation? -- Installation stalls randomly until a key is pressed https://bugs.launchpad.net/bugs/217815 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

Up to date hardy with kvm 1:62+dfsg-0ubuntu6 still hangs. Note that this time I tried it with the same command as I did in my last comment (eg, kvm/xtightvncviewer and not virt-manager). Last few times it stopped in 'Erasing data on SCSI1...'. Getting back to Soren's comment on default_idle-- whenever the install hangs, CPU utilization on the host by the guest goes to '0'. Normally during the installer it is around 100% on one of the host CPUs (when not waiting for a response from the user). Also note that if not using virt-manager and gtkvnc (ie you use xtightvncviewer or possibly other vnc clients), it seems all you have to do to get it unhung is drag the mouse over the window (the window does not need to be the active window either). This must be a difference between vnc implementations. So when testing this, be *very* careful about mouse movements over the installer window. -- Installation stalls randomly until a key is pressed https://bugs.launchpad.net/bugs/217815 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 217815] Re: Installation stalls randomly until a key is pressed
A couple of points worth mulling over to corner this one.. 1. Is the "hanging" a function of memory size - for example, the buffer cache filling up after a certain amount of time and then pdflush kicking in very aggressively doing dirty data writing backs as fast as it can. In which case, one may see the system resume again after a (long) period of time once pdflush is complete. It may be worth tweaking with the /proc/sys/vm/dirty* options to see if this trips the problem more frequently. Also, it may be worth seeing if doing the install with small memory kvm virtual machines shows this problem earlier than large memory virtual machines just to see if it is a buffer cache write back cpu starvation issue. 2. From my understanding dd is being used to zero the encrypted disk. Does changing the dd block size to a very large size trip this bug earlier as one gets more throughput than the normal (small) block size default? 3. Is the hanging resumed by an external interrupt (keyboard, mouse) because of the scheduler boosts interactive sessions temporarily and hence interfering (in a positive way) to the balancing of the encryption kernel space thread, dd and pdflush? -- Installation stalls randomly until a key is pressed https://bugs.launchpad.net/bugs/217815 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

During my kvm/qemu testing, even before Gutsy was released, I had similar problem - guest operating system would stall (both windows and linux) randomly when I would switch workspaces in GNOME, shift focus from application to application, etc... As soon as I would move focus back to qemu/kvm window, everything would continue. Sometimes even that wouldn't help. But, I never had those problems on my workstation, only on my laptop.

Re: [Bug 217815] Re: Installation stalls randomly until a key is pressed
Current thinking is that there are probably two separate issues here: 1. A problem specific to the KVM virtual environment 2. A problem specific to a particular hardware type. As such, I've un-duped bug 217849. -- - mdz -- Installation stalls randomly until a key is pressed https://bugs.launchpad.net/bugs/217815 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 217815] Re: Installation stalls randomly until a key is pressed
Stéphane Graber's comment about entropy got me thinking... Is there anywhere in the installation that depends on entropy (/dev/random or /dev/urandom)? Something like openssh-server would, of course, for key generation. But that's not a default package, and the installation/configuration thereof comes long after the point at which most of you are triggering this bug. So thinking much earlier in the installer, anything come to mind? Particularly something that might have been added since Gutsy as we now believe this is a regression? :-Dustin -- Installation stalls randomly until a key is pressed https://bugs.launchpad.net/bugs/217815 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 217815] Re: Installation stalls randomly until a key is pressed
This does appear to be a regression from 7.10 as I couldn't trigger the bug in the 7.10 installer. I will continue several more times and report back if 7.10 installs hang. -- Installation stalls randomly until a key is pressed https://bugs.launchpad.net/bugs/217815 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

For people trying Gutsy or earlier CDs in kvm, you have to update the iso.

[Bug 217815] Re: Installation stalls randomly until a key is pressed
Regarding 7.10 regression, I haven't tried gutsy installs with my vm, but I will and will post back. As for where it stalls, it is random places. I've seen it stall in 'Scanning for CD-ROM', different packages, pretty much anywhere between setting up the keyboard and the partitioner. I did see the hang in the partitioner as well. -- Installation stalls randomly until a key is pressed https://bugs.launchpad.net/bugs/217815 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 217815] Re: Installation stalls randomly until a key is pressed
Jamie, where does it stall for you, if not during the erase stage? My tests have all been on a Core 2 Duo T7500 and I haven't been able to reproduce the problem at all despite several test installations using alternate install CDs. Is this specific to the server kernel? ** Summary changed: - When selecting LVM Crypt, erase never ends + Installation stalls randomly until a key is pressed ** Description changed: - LATEST BUILD TESTED: - 20080416 - - Using Hardy Server 64bit - - Select Guided partioning LVM Crypt - - Erasing the partition never ends (stuck at 27%) and there no more disk activity (waited 10 minutes) - - One can press cancel and the installation continues... - - Test done under KVM (if it has an impact) + There are several reports, both in KVM and on real hardware, of a + problem where the installation process will stall, and no further + progress is made until a key is pressed.
