kernel: Unable to handle kernel NULL pointer dereference at virtual address 0000000c

After upgrading to Fedora Core 3 (from Fedora Core 1) one of my servers seems to be crashing at least once a month. Running kernel 2.6.11 for a week now the problems doesn't seem to be fixed...

Kernel:

Linux alpha.86id.nl 2.6.11-1.14_FC3smp #1 SMP Thu Apr 7 19:38:19 EDT 2005 i686 i686 i386 GNU/Linux

Crash log:

As you can see in the log, there seems to be a problem with the virtual memory:

Apr 22 13:00:06 alpha kernel: EIP is at __rb_rotate_left+0x8/0x3a

The harddisk, however, passed all tests I did. Any suggestions?


Best regards,

Pieter Zandbergen

How about memory tests? When you boot the Fedora installer you can enter memtest and test your RAM.

Or it could be the processor, but that's fairly rare.

Haven't ruled out softare yet, either, but it sounds like one faulty machine.

Both RAM (memtest86) and CPU (burn-in) test passed

We're seeing the same error on a FC2 machine, same Call Trace too. Any ideas? Did you find a fix?

Nope, I just installed debian on this machine and everything seems to work fine now.

We're having the same problem. We can normally go a few weeks between problems but it keeps coming back. This box has already bowed out twice today. Here are the 2 dumps:

Tyan Tiger i7505 board w/ dual 2.8Ghz Xeon processors.

Appears to be SMP related since we're all running that type of kernel.

We had a 2-3 day span where we lost this box a handful of times. It's now been up over 2 weeks without any more incidents.
