Description Derek Tattersall 1999-06-08 20:45:08 UTC
The poweroff command causes a kernel paging exceptionafter
the file system have been unmounted.

Comment 1 Derek Tattersall 1999-06-10 15:36:59 UTC
Also happens with halt and shutdown -h.  I have appended a ksymoops
report.
Options used: -V (default)
              -o /lib/modules/2.2.5-15/ (default)
              -k /proc/ksyms (default)
              -l /proc/modules (default)
              -m /boot/System.map (specified)
              -c 1 (default)

Comment 2 Bill Nottingham 1999-06-23 23:02:59 UTC
That's really bizarre. The code that it says it oopsed in is
the code that prints the oops dump.

If you take the '-p' out of the /etc/rc.d/init.d/halt script,
does it still oops?

Comment 3 Derek Tattersall 1999-06-30 14:17:59 UTC
Removing the -p from the eval $command -i -d -p statement and no
oops.  Any hints as to why this is AMD specific?

Comment 4 Bill Nottingham 1999-07-01 20:37:59 UTC
it's actually probably bios-specific

Comment 6 Bill Nottingham 1999-07-28 21:51:59 UTC
OK, there is a kernel patch which might help. However, here  it
just makes it reboot instead of oops.

Normally I'd suggest upgrading the BIOS, but that hosed the machine
I was using, so I wouldn't suggest doing that.OK, there is a kernel patch which might help. However, here  it

Comment 7 Bill Nottingham 1999-08-22 00:11:59 UTC
At this point, I'd chalk this up to a broken BIOS.

Comment 8 peterw 2000-01-21 02:36:59 UTC
Could you post a pointer to this mysterious patch? I'd rather fix this in my
kernel than flash my BIOS and pray nothing else gets hosed. :-(

Thanks.
