Kernel OOPS output
I have similar problems and they appear more seldom since i increased swapspace from approx 400 Mbyte to 600 Mbyte. I have 224 Mbyte ram and heard that swapspace should be at least the double, due to a bug... I have 256 MB of RAM and my swap file is nearly 550 MB. I upgraded my kernel to 2.4.5 a couple of days ago and have had only one hit since then. I also upgraded my BIOS to the latest one. I am suspicious of the VIA chipset on my motherboard. I have a ABit KT7A-RAID (nothing on the RAID controller at the moment). I have no direct evidence that it's the VIA but a lot of people have had problems with it. I've done some looking at the kernel source to try and determine what the pollwait routine does and see if it may be a chipset issue. Not much progress on that. When/if it happens again I'm going to telnet into the box and run ksymoops at the time of the failure and see if that reveals anything. At this point I'm waiting on another incident. Some bioses are known to misconfigure (in hindsight) VIA chipsets... if a biosupgrade fixed it it seems like a bios/chipset bug indeed. I'll mark this bug as "needinfo" so it's simple to reopen once this returns... Created attachment 21645 [details]
ksymoops output
Just when I thought this problem had disappeared, I had another occurance this evening. This time I telneted in and ran ksymoops of the running system before rebooting. I also captued the output from lsmod.

Can you try removing the lmsensors module ? Also, what kernel was this exactly ? I can remove the lmsensors module. I have taken the oops with and without those modules loaded. The kernel is 2.4.5. As noted before, the oops was happening daily with 2.4.2-2. After flashing the bios and upgrading the kernel the instances have become much less frequent (i.e. 2). I can't say which is responsible -- the bios upgrade or the kernel upgrade. My suspicion is the bios upgrade since there have been numerious problems with VIA chipsets.

ksymoops output for kernel 2.4.3-12
Since my last update I have had many occurances of this problem.... 7 yesterday and 3 today. All were without LMSENSORS loaded. This morning I backed off to kernel 2.4.2-2 (the original from Redhat 7.1). The hit this morning was taken with the 2.4.2-2 kernel. At noon I upgraded to the new 2.4.3-12 kernel. I took a hit this afternoon while it was running. I've included the ksymoops output as an attachment. I don't understand why I ran for nearly three weeks without incident. The only updates to the system were via up2date. Those were... SysVinit-2.78-17.i386.rpm XFree86-SVGA-3.3.6-38.i386.rpm XFree86-VGA16-3.3.6-38.i386.rpm cpp-2.96-85.i386.rpm gcc-2.96-85.i386.rpm gcc-c++-2.96-85.i386.rpm libstdc++-2.96-85.i386.rpm libstdc++-devel-2.96-85.i386.rpm I have no idea if this is a hardware problem or a software problem. The problem is always at __pollwait+16. I have no idea what that routine does. This problem should be closed. It turned out to be a bad CPU!!! The processor chip was replaced and all is well. Thank you for letting us know. Bad hardware is not something I can fix ;) |
