OK, I've been working on various incarnations of this problem for a week now... I have another day or two and then I'm gonna have to go back to NT... Sigh... [Help me, PLEASE...!] I have a PC (550 MHZ P-III, Asus P3B-F, 256 MB) with two Adaptec 2940U2W boards with six IBM DMVS36V 36GB drives. I also have a four gig internal SCSI drive attached to the first 2940U2W to boot from. The goal is to use vinum and create a RAID5 system... OK, I have installed FreeBSD 4.0 from the CD that I was shipped. I then try to use disklabel to put a label onto the first 36GB drive, like so: disklabel -Brw da1 auto but the SCSI bus times out and then I'm hosed. I get the following messages: (da1:ahc0:0:1:0) SCB 0x0c - timed out in Data-out phase, SSEQADDR == 0x5d (da1:ahc0:0:1:0) BDR message in message buffer (da1:ahc0:0:1:0) SCB 0x0c - timed out in Data-out phase, SSEQADDR == 0x5e (da1:ahc0:0:1:0) BDR message in message buffer (da1:ahc0:0:1:0) no longer in timeout, status = 34b ahc0: Issued Channel A Bus Reset. 4 SCBs aborted And a screen full of similar messages. (I have to copy them over by hand, but I'll do it if it means solving this problem.) The internal disk seems to go into a timeout as well. (da0:ahc0:0:0:0) After a few minutes, the command prompt comes back, and I can type "disklabel da1" and get what looks like a valid reply. I can also run disklabel -e and add another partition, but if I try to use newfs, I get the same timeout problems. I've tried this with disks attached to the other 2940 with the same results. (Except that the internal drive doesn't time out in that case...) If I try to reboot the computer at this (or any other) point, it freezes with the following message: int=00000000 err=00000000 efl=00030246 eip=00001b54 eax=00000000 ebx=00000386 ecx=00000000 edx=00000000 esi=00009ebd edi=00001a3e ebp=0000038e esp=00000382 cs=d000 ds=0040 es=9ebd fs=0000 gs=0000 ss=9ebd cs:eip=f7 f1 33 d2 8a 4e f6 f7-f1 3d ff 03 76 03 b8 ff ss:esp=00 00 3f 00 00 00 00 00-00 00 02 00 df 09 00 d0 system halted I get this message whether I reboot immediately after the first disklabel command, or if I reboot after using disklabel to add a partition, or after using newfs. I get the same message whether I try to boot from the system on the hard disk or from the 4.0 CD-ROM. I get a similar message when trying to boot from a 3.4 CD. At this point, the only way I can do anything is to reboot, hit ctrl-A to get into the Adaptec diagnostics and reformat the 36 GB hard disk at that level. Then I can reboot and FreeBSD starts right up from the internal hard disk where it was originally installed. What gives?
