strange SysRq problem

[Hans-Peter Jansen]

Hi,

I'm suffering from a strange SysRq problem:

syslog shows haphazardly "SysRq : HELP" lines, while I definitely didn't 
triggered them, neither via (PS/2) keyboard, nor via /proc/sysrq-trigger.
This is accompanied with stalls of about 15-60 secs. 

Here's an example:

Feb 14 00:16:11 xrated kernel: SysRq : HELP : loglevel0-8 reBoot Crashdump 
tErm Full kIll saK showMem Nice powerOff showPc show-all-timers(Q) unRaw 
Sync showTasks Unmount shoW-blocked-tasks 
Feb 14 00:32:45 xrated kernel: SysRq : HELP : loglevel0-8 reBoot Crashdump 
tErm Full kIll saK showMem Nice powerOff showPc show-all-timers(Q) unRaw 
Sync showTasks Unmount shoW-blocked-tasks 
Feb 14 00:32:57 xrated kernel: SysRq : HELP : loglevel0-8 reBoot Crashdump 
tErm Full kIll saK showMem Nice powerOff showPc show-all-timers(Q) unRaw 
Sync showTasks Unmount shoW-blocked-tasks

tErm Full kIll saK showMem Nice powerOff showPc show-all-timers(Q) unRaw 
Sync showTasks Unmount shoW-blocked-tasks 
Feb 14 00:33:33 xrated kernel: SysRq : HELP : loglevel0-8 reBoot Crashdump 
tErm Full kIll saK showMem Nice powerOff showPc show-all-timers(Q) unRaw 
Sync showTasks Unmount shoW-blocked-tasks 

Anybody suffered from similar behavior out there, and tracked it down?

TIA,
Pete
