Greetings,
I'm getting a pretty consistant oops under 2.6.17 which looks to be
associated with tty_write. Same box works just perfectly under
2.6.16. Technically these are stock Debian kernels but I don't expect
it's something in the Debian patches. It could be a vserver issue but
that also seems unlikely to me.
The kernel command-line would have looked something like this:
Kernel command line:
root=/dev/md0 ro earlyprintk=serial,ttyS0,9600,keep console=tty0 console=ttyS0,9600
Note that I modified that command-line a number of times and continued
to get an oops (I don't know for sure that it was always the *same* tho,
and I only have serial-console access, but it didn't come all the way up
when booted w/o earlyprintk= or console= arguments, of course, that
could have been due to something else too).
Unfortunately, I didn't grab the full boot log. If that's necessary then
I can look into finding a time to do that (it's a production server tho,
so folks aren't exactly keen on my rebooting it a bunch).
Here's the oops:
