Subject: BUG: sleeping function called from invalid context at kernel/fork.c:385
Date: Wed, 23 May 2007 16:31:54 +1000 [thread overview]
Message-ID: <20070523063154.GR85884050@sgi.com> (raw)
Saw this when running strace -f on a script on 2.6.21 on ia64:
BUG: sleeping function called from invalid context at kernel/fork.c:385

I could reproduce it via 'strace -f sleep 1'
