Ragnar,
Are you sure that was line 115? Could it have been line 515?
Also, do you have any Oops data?
Thanks,

Yesterday BUG in schedule at 515 happened for me with test12-pre4.
As there were no data, and it was followed by
NMI detected lockup on CPU24 ...
(without any further data... no stack trace), I throwed it away as
some -pre4 memory corruption. Maybe it was not random corruption, but
stack overflow? Of course, my machine does not have 25 CPUs, but only
two PIII...
And no, I have no oops data. I was reviewing Debian changes
(apt-listchanges) when picture scrolled up one line (bug in sched) and
then, after 5 seconds, another one line, with 'NMI detected'... And
that was all, time to hit reset.
It was very patched test12-pre4, it contained Al Viro & Sct dirty buffer
patches, Andrew Morton's exec_usermodehelper, and couple of other
patches, brutto 153KB unzipped unified diff.
Filesystem ext2, 256MB RAM, dual PIII/450, kernel compiled with Debian's
gcc-2.95.2, matroxfb. On background there were Debian's XF4.0.1-9
running with Gnome and DRI, as I was tracking why that beast reprograms
matrox hardware every second (or every minute, depending on format of
clock in left upper corner; but that's another story) even if X are not
visible... (btw that's reason, why matroxfb does not work correctly with
XF4 & DRI...)
Best regards,

Yes, yes, it was 515. 115 is the result of human cache corruption ;)

It just froze there.
