Hi all,
And Happy New Year! May 2008 bring us less bugs :-)
Please Cc me, as I am not subscribed anymore.
I recently upgraded the kernel of one of my servers to a vanilla*
2.6.23.12 and had it running for a few days (vanilla*, 'cause I change
the Makefile to use distcc).
After some time I got "invalid opcode: 0000" MSG and as this was just in
time for some AC maintenance, I rebooted the machine, ignoring it. Now I
got exactly the same error again, so I decided to post here.

:-( there are lots of sh processes, so I have no idea how to trace it. I
grepped through all the logs in that window, but nothing unusual popped
up.
Can anyone suggest a good way to trace that?
I had a look at the code [1], but that was beyond my asm skills :-|
