Subject: 2.4.22 ACPI power off via sysrq not working
Date: Fri, 03 Oct 2003 10:12:58 +0200 [thread overview]
Message-ID: <1065168778.1740.10.camel@highscreen> (raw)
Hi,
If I want to halt the system using sys-rq - o key, I get an oops instead
of a power down.
Inside pm.c:159, there is:
if (in_interrupt())
BUG();
But if we look at the trace, we are in the interrupt of the keyboard
handler.
One fix would be to comment out the BUG line, but there's certainly "a
better way to do it".
Sylvain
