We get a coupld of messages like this per day: sd0(ahc0:1:0): SCB 0x2 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 SEQADDR = 0x5 SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT1 = 0xa sd0(ahc0:1:0): SCB 2: Immediate reset. Flags = 0x1 ahc0: Issued Channel A Bus Reset. 2 SCBs aborted Clearing bus reset Clearing 'in-reset' flag sd0(ahc0:1:0): no longer in timeout sd0(ahc0:1:0): UNIT ATTENTION asc:29,2 , retries:3 sd2(ahc0:3:0): UNIT ATTENTION asc:29,2 , retries:4 sd1(ahc0:2:0): UNIT ATTENTION asc:29,2 , retries:4 The question is, what does this indicate? sd0 is an 4GB Fujitsu 2940 Ultra. sd1 and sd2 are 4GB Fujitsu UltraWide. the controller is an 2940UW. We am running FreeBSD 2.2.2. The number of errors seems to has increased significantly when we swapped the CPU from P6/200MHz stepping 7 to P6/200MHz stepping 9, and at the same time downgrading memory from 128MB to 64MB. But that might be a coincidence, or course. Torbjorn
