Default Bug#596419: Same issue in lenny

Hey there,



I am not sure if this is the best place to chime in, but here goes:



I am having the same issue in lenny/5.0 with version of 2.6.26-26lenny1
xen-linux-system-2.6.26-2-xen-amd64 on several identical servers
running Xen. It seems the aacraid driver is at fault and dies on the
same line of 'drivers/scsi/aacraid/aachba.c'. This seems to occur
during periods of extreme IO/CPU load when we run duplicity on our
database data, but this is an observation and could be incorrect.



Here is two traces from two servers experiencing this issue:
