Package: linux-image-2.6.18-5-sparc64
Version: 2.6.18.dfsg.1-17
Severity: minor

Hi,

I have Sun Ultra5 running Etch. Sometimes, I see kernel message like:
Kernel unaligned access at TPC[45dc5c] handle_futex_death+0x20/0x90

For example, I reboot today in 2.6.18-5-sparc64:

--8<--
ultra5:~# tail /var/log/kern.log

Severity is minor because I haven't noticed anything 
being affected by this message.

No further feedback, please reopen if the problem persists in more
