Maybe it's a totally different issue, but I also noticed system lockups, that started after I converted the system to Software-RAID1. However, in my case the lockups only occur after 3-10 days uptime. One day I was able to capture a couple of syslog entries: | Jun 12 09:50:47 tardis kernel: hdg: lost interrupt | Jun 12 09:50:47 tardis kernel: hdg: drive_cmd: status=0x51 { DriveReady SeekComplete Error } | Jun 12 09:50:47 tardis kernel: hdg: drive_cmd: error=0x04 { DriveStatusError } | Jun 12 09:50:47 tardis kernel: ide: failed opcode was: 0xb0 | Jun 12 09:51:07 tardis kernel: hdg: dma_timer_expiry: dma status == 0x21 | (2 x WD2500SB-01RFA0 on a PDC20276 (MBFastTrak133)) The HDD LED is permanently on.
