Red Hat Bugzilla – Bug 606582
fedora completely unstable under high network traffic or disk usage

output of lshw
Description of problem:
After upgrading to Fedora 12 my system has become increasingly more unstable. It crashes, completely locking up so I have to hit the reset button, almost daily. On some days I get a series of kernel OOPSes just before the lockup. They are always something to do with spinlock errors, memory management errors, etc. I have reported almost 20 of these to kerneloops.org using ABRT.
These crashes almost always happen when I running something that does a lot of network access (like deluge) and/or writes to disk alot (like transcode). Sometimes it happens when watching a DVD or flash video (Youtube for example).
Version-Release number of selected component (if applicable):
Every kernel since Fedora 12 was released. Currently using:
Steps to Reproduce:
1. boot machine
2. run program that uses lots of network or disk
3. after a while machine crashes
I have been able to reduce the frequency of crashes by disabling ksm and kernel mode setting.
I am attaching the output of lshw.

Could you please give us link for them. Or attach logs with messages here. Ideally if you could run debug kernel, and attach dmesg including first oops/calltrace.

Stop to use any proprietary modules, we do not support tainted kernels. If problem still happens provide dmesg. This time please attach full dmesg: from system start to oops.
Random errors like that could also be due to memory failures. Try running memtest overnight.
I'll repost without the NVidia module loaded... however be aware that the problem happens the same when using the nouveau driver.
The problem is that usually there is no OOPS... the machine just locks up and I have to hit the reset button. So to get an OOPS trace I have to play with loading the system until it crashes "softly". Might take a few days.
I'll do the memtest tonight.
Please post the boot messages (contents of /var/log/dmesg).
Execpt providing boot dmesg, please configure kdump (http://fedoraproject.org/wiki/Kernel/kdump or use system-config-kdump). This should allow to crash memory when system hung and get additional info from memory dump.
Hi Harris, could you provide additional info requested in comment 6 and 7 ?
Sorry I didn't get back to this... performed the memtest as suggested by Chuck. Turns out I had a faulty DIMM :-( DOH!! Have been running for a while now without incident.
You can mark this one closed I think :-)
