I'd check the aic7890 specific I just upgraded my system to the latest -current today, from a long hiatus... last time I did a world was July 3rd. I can no longer boot the system. I was beginning to sort through the boot floppies, to figure out when the changes were made that sunk me. Thanks for saving me the trouble. :) I'm booting off the onboard AIC7895 on a Tyan Thunder/100. I get the same error you do initially, followed by many, many SCSI bus resets, errors about lost devices, SCBs aborted, and the like. After a period, the system panics... not about being unable to mount the root fs like I expected, but about 'page fault in kernel mode' or something similar. (da0:ahc0:0:0:0): SCB 0x9 - timed out in Command phase, SEQADDR == 0xa0 (da0:ahc0:0:0:0): BDR message in message buffer (da0:ahc0:0:0:0): SCB 0x9 - timed out in Command phase, SEQADDR == 0x9f (da0:ahc0:0:0:0): no longer in timeout, status = 34b ahc0: Issued Channel A Bus Reset. 4 SCBs aborted etc... Finally it ends with 'Fatal trap 12: page fault while in kernel mode' fault virtual address = 0x3c fault code = supervisor write, page not present The machine locks up hard at that, needing a power cycle. The SCSI activity light blazes. Sorry I can't cut'n'paste the errors to be more useful, I don't have a serial console. I'm copying them by hand as best I can (I'd appreciate being told a better method... :) ) -- Brandon Hume - hume -> BOFH.Halifax.NS.Ca, http://WWW.BOFH.Halifax.NS.Ca/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
