Oops in 2.0.8

This is with an ELF kernel compiled with GCC 2.7.2 and binutils
Libc is 5.2.18 and ld.so is 1.7.14. SysVinit is at 2.64. Other stats are
as my previous post about an oops in 2.0.6. The system was only up for
about 12 hours before this oops struck. The system seems to be
unaffected, but I'll be rebooting it on the general principle of the
thing. :)

The ext2 filesystem in question resides on a 4GB SCSI drive hanging off
an Adaptec 1542.

More information can be supplied upon request.

You will be surprised by a loud noise.
