John-Mark Gurney scribbled this message on Nov 25: looks like I left out an important part of the log: (da0:ncr0:0:0:0): phase change 2-3 10@038ee29c resid=4. (da0:ncr0:0:0:0): WRITE(10). CDB: 2a 0 0 3f 8a e0 0 0 60 0 (da0:ncr0:0:0:0): ILLEGAL REQUEST asc:24,0 (da0:ncr0:0:0:0): Invalid field in CDB which happened about at least six minutes before the following started (can tell by syslog messages to the console) > ncr0: timeout nccb=0xc0d92000 (skip) then later in the add (after a reboot), a similar event happened: ncr0: SCSI phase error fixup: CCB address mismatch (0xc120ac00 != 0xc11fca00) np->nccb = 0xc120ac00 (da2:ncr0:0:4:0): phase change 6-3 3@03efbdb4 resid=3. ncr0: queue empty. ncr0: SCSI phase error fixup: CCB already dequeued (0xc120ac00) ncr0: timeout nccb=0xc0f05800 (skip) ncr0: timeout nccb=0xc0f05a00 (skip) ncr0: timeout nccb=0xc0ecb800 (skip) ncr0: timeout nccb=0xc0ecbc00 (skip) ncr0: timeout nccb=0xc120ac00 (skip) which is kinda interesting, as it looks like the ccb that caused this isn't even valid (the head disaggress what virtual address it is at..) of course, I'm having troubles wrapping my head aroun the ncr driver as most of it isn't commented very well.. the last lockup had this on output: (pass1:ncr0:0:1:0): MSG_DISCONNECT received, but datapointer not saved: data=2274d90 save=e71026a0 goal=e71026c4.
