Subject: [uml-devel] FYI: Re bug report [ 745826 ] run cat /dev/urandom
Date: Sun, 07 Nov 2004 18:34:25 +0100	[thread overview]
Message-ID: <418E5CA1.90308@praguespringpeople.org> (raw)

Posted to SourceForge:

For the record, this is not entirely fixed. I'm running a Debian host
with 2.4.25 kernel and host-skas3-2.4.25.patch, and a Debian
guest with 2.4.27 kernel and uml-patch-2.4.26-3.

In one xterm I ran "while true; do ls -la /dev/*; done" (see
also bug report 617709). In the other, "cat /dev/urandom".
After 5-10 seconds, the 'linux' host process crashes
completely with:

Scheduling in interrupt
Kernel panic: kernel BUG at sched.c:564!

In interrupt handler - not syncing
