Dear Sirs. On one machine I changed today an Adaptec 2940UW with Adaptec 2949U2W. Both controllers worked with FreeBSD in the same server long time before, but with several different harddrivedisks. Last week we changed a machine's drives and I got a spare IBM DDRS 39130D 8,5 GB LVD disk. This disk is now attached to the Adaptec 2940U2W controller. The box is a FreeBSD 4.3-RC2 SMP box. The kernel starts the normal way, but when initializing the SCSI bus there occurs an error, a lot of errors about 'untagged' statements and several 'SCB 3 3 4 ...' statements occur. I can not dump this, it's to fast on the screen. End of this procedure is a reboot of the kernel. I tried a GNERERIC kernel and tried to start a single user mode session because I think there is a problem with the tagged queuing command cache of the disks 9I would like to disable it, but it seems to be impossible). On the other hand, maybe the controller is damaged but it worked before well with other LVD disks (IBM DNES ...). Is there a trick to start the SCSI system without enabling tagged queuing command caches ? Oliver -- MfG O.
