Well I do have another oops now (artsd this time). Once again it's in del_timer_sync in 2.4.4, same computer after a reboot, same kernel. It is a UP system (SMP kernel) btw.
Could it be that the aic7xxx driver is improperly destroying a timer? I am having some problems with a scanner attached to the SCSI card in question that usually result in the driver setting the scanner inactive until I reset the scanner and rmmod/insmod the driver again.
