Subject: how can I touch softlockup watchdog on all cpus?
Date: Wed, 21 Mar 2007 17:06:34 +0100	[thread overview]
Message-ID: <> (raw)


my module generates this ugly softlockup dump, because all cpus are stopped longer then 10 secs.
What I do is:
// my stuff which takes long and stopps all cpus

this prevents a dump of my current cpu but not for all.
A call to smp_call_function with a function which calls touch_softlockup_watchdog in it,
doesn't work because smp_call_function needs to be done with irqs enabled, so the watchdog comes first :(.

Any hints or ideas how I can do it in a better way? Disabling softlockup watchdog is not possible for me.

Ciao Thilo
