I'm trying to track down why I'm seeing this kind of error in our log files: swap_pager: indefinite wait buffer: device: #da/0x20001, blkno: 608, size: 4096 swap_pager: indefinite wait buffer: device: #da/0x20001, blkno: 7568, size: 4096 We're running -stable with an Adaptec 2110S RAID controller and three disks on SCSI ids 3, 4, and 5 in a RAID5 configuration. Running "raidutil -e nonrecov d0" shows several sequences like the following (separated by varying amounts of time). Every time, the initial "Bad SCSI Status - Check Condition" comes from id 5. Can anyone interpret the initial "bad scsi status" that kicks off the bus reset, etc.? Whatever it is, it isn't degrading the volume, but if a disk is going bad or if there's some other problem I would like to know. Thanks in advance for any help you can offer.
