Subject: 2.6.14-git3: scheduling while atomic from cpufreq on Athlon64
Date: Mon, 31 Oct 2005 16:06:36 +0100	[thread overview]
Message-ID: <200510311606.36615.rjw@sisk.pl> (raw)

Hi,

I'm getting some "scheduling while atomic" messages from 2.6.14-git3 on boot
and on suspend/resume, eg.:

NET: Registered protocol family 1

Additionally there are some problems with freezing processes by swsusp.

Greetings,
