I am seeing a lot of this kind of stuff _only_ when the system starts swapping: Nov 13 19:48:25 rhiannon /kernel: ahc0: WARNING no command for scb 1 (cmdcmplt) Nov 13 19:48:25 rhiannon /kernel: QOUTCNT == 1 Nov 13 19:48:35 rhiannon /kernel: sd1: SCB 0x0 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 Nov 13 19:48:35 rhiannon /kernel: SEQADDR = 0x5 SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT1 = 0xa Nov 13 19:48:35 rhiannon /kernel: Ordered Tag queued Nov 13 19:48:35 rhiannon /kernel: Ordered Tag sent Nov 13 19:48:40 rhiannon /kernel: sd1: SCB 0x0 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 Nov 13 19:48:40 rhiannon /kernel: SEQADDR = 0x7 SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT1 = 0xa Nov 13 19:48:40 rhiannon /kernel: sd1: Queueing an Abort SCB Nov 13 19:48:40 rhiannon /kernel: sd1: Abort Message Sent Nov 13 19:48:40 rhiannon /kernel: sd1: SCB 0 - Abort Tag Completed. Nov 13 19:48:40 rhiannon /kernel: sd1: no longer in timeout I never get this kind of thing when no swapping is going on, no matter how heavy the disk load is. Ideas?
