Re: [expert] Memory problem? Memtest86 question
Are you indicating that 9.0 doesn't support anything other than ext2 or ext3? If so, Where's the BEEF? Do you have any Documentation available? Mandrake 9.0 supports reiserfs. Personally, I've been using reiserfs on all my partitions save one since roughly version 8.0 or 8.1. I've yet to experience a problem. Regarding kernel errors and the like, those may or may not be caused by specific versions and builds of the linux kernel, and whether or not one should be running a particular version (especially bleeding- edge development kernels) or if such version should be built with gcc 3.x to me is a question best answered by those on the linux kernel mailing list. I don't see how Mandrake should expect to support odd kernel releases. All in all, the kernel in 9.0 is stable - my system has been up for over 3 months now. I rebooted it 3 months ago to install 9.0 :) 7.2 was pretty stable as well - over 180 days uptime on it before I rebooted. Want to buy your Pack or Services from MandrakeSoft?

Re: [expert] Memory problem? Memtest86 question
I am curious as to Which OS Version you encountered this? I have a Sever running for Several Months on LM 8.2, when I install LM 9.0 it will not rung for more than a few days without encountering this message. Any ideas? Praedor Tempus Atrebates wrote: Some of what I have found with regards to messages like: Unable to handle kernel paging request at virtual address 01100112 is that it is thought to be related to memory/cache problems. Does anyone know one way or another? I have been running memtest86 for over an hour on the problem system and so far there have been no errors. Anyone have experience with a similar error message and use of memtest86? Does this error type usually show up running memtest or is there something else going on. I have rebuilt my kernel, rebuilt the wlan driver, disabled and enabled APIC, all to no avail. The module for the wusb11 loads and KControl identifies it properly. What doesn't happen is that devfs doesn't create a device for the wlan device as it should and no amount of unplugging/replugging the wusb11 does any good. I cannot even unload the module for the device because I always get back a "device busy or in use" message. Is there any way to force a module to unload no matter what? It may not be pretty but it has to be better than having to reboot. Shutting down usb doesn't permit unloading the wusb11 driver either. praedor Want to buy your Pack or Services from MandrakeSoft?

I am using a ReiserFS Filesystem on my server as well. Are you indicating that 9.0 doesn't support anything other than ext2 or ext3? If so, Where's the BEEF? Do you have any Documentation available? I never got any answers from support either, must have been the Chapter 11 filing issues . Would like to get the 9.0 running on it, but I have no idea what will provide support for the ReiserFS filesystem. Any Suggestions? -- Albert E.

I have gotten my WUSB11 working after much pulling of hair and gnashing of teeth but I am not sure the kernel paging issue is really fixed or if it just decided not to rear its head with my last restart. praedor -- Conservatives of all times are adventitious liars. - Friedrich Nietzsche.

The problems are in the kernel code and in gcc3.x. If you want your software to WORK, don't use gcc3.x. If you want it to run faster, perhaps not compile, perhaps NOT work, use gcc3.x.

Does anyone know one way or another? I have been running memtest86 for over an hour on the problem system and so far there have been no errors. memtest86 is very lightweight. Even it's name is misleading as there is no software test for just memory. When you run a diag on a system, the cpu/cache (both L1 and L2)/motherboard chipsets/ram all have to work together to produce no errors. A better test is, ftp://mersenne.org/gimps/mprime2212.tar.gz Quick start: unpack to a dir, look for the executable mprime*. run it with ./mprime, it'll ask if you want to join the prime search or just test, opt for test. Then run it with ./mprime -m and choose number 17, the torture test. If it encounters any hardware errors, it'll exit an tell you so. BTW, if you're curious about mprime, http://www.mersenne.org/prime.htm The acid test, http://users.ev1.net/~redelm/ While it's billed as a cpu test, as I alluded to above, it stresses the whole system. If you can run cpuburn's modules appropriate for your system or an hour, your system is bulletproof IMO, cpuburn is the quickest way to determine if you need to start lookin at OS (kernel) and software for the root of your problem. But, you should see if you can run mprime's torture test for an hour or two first. -- Tom Brinkman Corpus Christi, Texas Want to buy your Pack or Services from MandrakeSoft?
