Description Randy Dunlap 2006-02-08 19:24:33 UTC 
syslog-ng is not stopped, then suspend fails, system comes back to life.
This is the default SMP installed kernel:
Linux version 2.6.16-rc1-git3-4-smp (geeko@buildhost) (gcc version 4.1.0 20060109 (prerelease) (SUSE Linux)) #1 SMP Tue Jan 24 16:43:20 UTC 2006

syslog during this time:

Comment 1 Randy Dunlap 2006-02-08 19:31:05 UTC 
Hm, powersave -U works on the second attempt (no reboots).
Did syslog-ng get killed but at the wrong point in time?
Comment 2 Greg Kroah-Hartman 2006-02-09 01:23:58 UTC 
Pavel, suspend issue?
Comment 3 Pavel Machek 2006-02-09 09:14:29 UTC 
Is it random failure or does it systematically break at first try and work on second try?

What hardware is that? (Just curious :-).
Comment 4 Forgotten User ZhJd0F0L3x 2006-02-09 13:47:23 UTC 
Holger did some tests on SMP (dualcore) so maybe he has seen something similar...
Comment 5 Randy Dunlap 2006-02-09 17:17:37 UTC 
I've seen it more than one time but it's not consistently repeatable.
IOW, powersave -U often (usually) succeeds.
Hardware is a Yonah (Core Duo) development board.
Comment 6 Pavel Machek 2006-02-10 20:18:43 UTC 
There are some improvements in recent -mm kernels. You could try if they help, but unless problem is reproducible I'd rather leave it as-is.
Comment 7 Pavel Machek 2006-03-03 20:18:34 UTC 
Randy, ping? Should I just mark it WORKSFORME or WONTFIX?
Comment 8 Pavel Machek 2006-03-27 09:39:44 UTC 
Randy is not responding, and I think this one is fixed.
