Bug#711294: random lockups
Package: linux-image-3.2.0-4-sparc64-smp
Version: 3.2.41-2+deb7u2
Severity: important
Hi,
smetana.debian.org, running our wheezy 3.2 kernel, locks up regularly.
It runs quite reliably using the squeeze kernel.
When it locks up it still responds to pings but one cannot login.
I saw this on the console last time it had this problem:

That message never made it to /var/log on the host itself or to the loghosts.
This bug might be the same as #648766. If so, please merge.
