I'm seeing the same thing on a Netra, using the 2.6.18-4-sparc64 kernel.

The Netra serves as a name server (BIND) and I haven't noticed anything 
being affected by the unaligned access messages.

Besides the already mentioned 'filldir64' messages, I have also seen 
'cp_compat_stat64' messages a couple of times. 

'filldir64' mostly happens around 06:25. Seems to me like a cron.daily job
is triggering it...
