They even mentioned in a previous firmware README that you should increase the timeout in the Linux SCSI driver to avoid this problem :-) Mvh, Frode On Jun 12, 2004, at 12:08, Eirik Oeverby wrote: > Hi all, > > I have recently been getting the following messages on my console: > swap_pager: indefinite wait buffer: device: #amrd/0x20001, blkno: > 1072, size: 4096 > swap_pager: indefinite wait buffer: device: #amrd/0x20001, blkno: 832, > size: 4096 > swap_pager: indefinite wait buffer: device: #amrd/0x20001, blkno: 512, > size: 4096 > swap_pager: indefinite wait buffer: device: #amrd/0x20001, blkno: 576, > size: 4096 > swap_pager: indefinite wait buffer: device: #amrd/0x20001, blkno: 584, > size: 4096 > > I am aware that this usually indicates a bad drive or something, but > given that it's a RAID volume hanging on an AMI MegaRAID controller > (SCSI), and none of the drives in the array are degraded, that can't > really be the case.
