I just tried 2.6.13-rc6 after my last 2.6.11.12 and got a problem with
the onboard aic7xxx on my old Gigabyte-6BXDS dual i686-600: During boot,
something bad happened within domain validation and I got an oops from
an unhandled NULL pointer. Since I don't have a secondary computer at
home to capture the OOPS, here's the shortened stacktrace written down
by hand:
show_stack
show_register
die
do_page_fault
error_code
ahc_set_syncrate
ahc_reset_channel
ahc_linux_bus_reset
scsi_try_bus_reset
scsi_eh_bus_reset
scsi_eh_ready_devs
scsi_unjam_host
scsi_error_handler
kernel_thread_helper

After chaning the Adaptec bios setting for the Pioneer CDROM from
"async" to "10 MB", I was able to boot the same kernel without problems.

If somebody needs more information, I can reproduce the OOPS again and
provide the missing information.

BYtE
Philipp
