Hello,
Not sure this is still important as the kernel is a bit old (2.6.18-4-sparc64-smp)
but I run into an oops on dual sparc64. The box is SUN ULTRA 60 - USII 2 x 450MHZ.
Unable to handle kernel paging request at virtual address 00000000703ce000
tsk->{mm,active_mm}->context = 000000000000021c
tsk->{mm,active_mm}->pgd = fffff8009ac02000

The kernel is default from debian etch.
Second issue is that kernel hangs from time to time but it looks like the i/o to the scsi disk is dead.
I installed fresh etch, downloaded 2.6.23-rc1-mm2, started compiling allmodconfig and it hung after a while.
After reboot the ext3 partition was messed up and reinstall was needed.
Is this a known issue? Should I just upgrade and forget?
Regards,
Mariusz
