It is worse:
status: One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
using 'zpool clear' or replace the device with 'zpool replace'.
scrub: none requested

These are WDC WD3200AAKS-00SBA0/12.01B01 connected to an SIL3114.
System is amd64 from 26th june on core2quad with ECC RAM.
My home system is using the same controller on i386/P3 and has no
checksum errors - it is running source from 12th july.
Considered that I'd seen lots of silent data corruptions with PATA
disks on alpha during the last years I'm not that shure if the problem
depends on a specific controller, but more on timing or such.
It is easy to blame the controller, especially since SIL isn't known
for quality, but in this case I believe it is our problem somehow.
