Package: linux-image-2.6.26-2-sparc64-smp
Version: 2.6.26-17
Severity: important

I'm continiously getting these kernel messages while running several IPSec tunnels:

[3881706.284682] Kernel unaligned access at TPC[10276320] copy_to_user_state+0x50/0x9c [xfrm_user]
[3881706.403493] Kernel unaligned access at TPC[10276330] copy_to_user_state+0x60/0x9c [xfrm_user]

It doesn't seem to affect any functionality, as tunnels are up and running.

Thanks; marking accordingly.

Would you be able to try some kernels from in between from
http://snapshot.debian.org/ to narrow down which version introduced
the fix?  E.g., a test with a v2.6.33 kernel would be interesting
already.  Once we find the relevant patch, we can try applying it to
squeeze.

Happy new year,
Jonathan
