Subject: RE: System Hang During tar Backup
Having updated today - or rather tried to - I'm now seeing similar
problems. Keyboard input is obviously active, and the console driver
will let me switch virtual ttys, but no user processes seem to be
getting any cpu. There's no tape drive involved in freezing the
system, just disk activity across multiple devices on the
controller. In particular, I've got:
<SEAGATE ST39236LW 0004> at scbus0 target 0 lun 0 (pass0,da0)
<SEAGATE ST39173W 5958> at scbus0 target 1 lun 0 (pass1,da1)
attached to:
<Adaptec aic7890/91 Ultra2 SCSI adapter> port 0xe800-0xe8ff mem
0xfebff000-0xfebfffff irq 10 at device 14.0 on pci0
I can get it to freeze reliably - meaning every time I tried to start
X - on a kernel supped earlier today, wherease the one from June 24th
has no problems.
I've got a debugging kernel built, but don't know if I'll have time to
do any work on this in the next two weeks. I should be dealing with
email, though.
James, you might report your hardware configuration as well.
