Kernel bug at boot

[eelco]

I installed FC2T2 recently. Installing the thing went allright, more or less, and the first few times i booted the machine it started fine. But now i get a kernel bug somewhere around entering runlevel 5.

Sometimes it shows a message about a kernel bug:

------------[ cut here ]------------
kernel BUG at fs/proc/generic.c:664!
invalid operand: 0000 [#1]
CPU: 0
[...]


Now, i would want to report this bug in bugzilla, but i can't find the messages in any log files. For example, dmesg just ends where the bug output began.

Can anyone tell me where to look for this kind of output?

If the boot continues normally you should be able to find that error in /var/log/messages or in /var/log/boot.log.

Hi,

I recieved the same messages.

You can find it with 'dmesg'.

Unfortunately, the boot process stops at the bug. Booting in FC1 gave me a chance to look around on the FC2T2-partition, but apart from dmesg, no intreresting files had been changed, and the bug output was not in dmesg.

Oh well, i'll just use a camera.

Try booting into single user level (for a howto see
