Senate and People of the FreeBSD Republic: I just upgraded from the February SNAP release to the June one, and compiled a hot-off-the-net 3.0-current kernel. By all accounts, that *should* have gotten me the latest, fixed version of the ahc driver, right? At least I thought so based on the numerous threads recently about it. However, when I then tried running cdd, it said: > cd1: SCB 0x1 - timed out while idle, LASTPHASE = 0x1, SCSISIGI = 0x0 > SEQADDR = 0x7 SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT1 = 0xa > cd1: Queuing an Abort SCB > cd1: Abort Message Sent > cd1: SCB 1 = Abort completed. > cd1: no longer in timeout > cd1: SCB 0x1 - timed out while idle, LASTPHASE = 0x1, SCSISIGI = 0x0 > SEQADDR = 0x4 SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT1 = 0xa > cd1: SCB 1: Immediate reset flags = 0x1 > ahc0: Issued Channel A Bus Reset, 1 SCBs aborted (from scribblings on paper; I think I have all the numbers right, but punctuation etc is approximate). What follows is a hang, not panic, and it's definitely a system hang, not a SCSI hang, because I can't even switch virtual consoles or press ^C. What gives? Looks like a return of the problems in April to me. Is this a known bug, or should I try and get a crash dump and start working on it? For reference, I have an Adaptec 2940AU controller, and cd1 is a Toshiba 3401 2x CD-ROM drive. The program that crashes it is cdd-1.0-970519. I'd be very grateful to anyone who has any suggestions on this! ~Ben
