[-- Attachment #1 --] We're trying to set up a server using dual P133 processors with the SMP kernel of Free BSD 3.0. The server is equipped with a DPT PM2144w SCSI host adapter to which is connected a 9 GB Seagate HD. There are no IDE devices although support for an IDE CDROM drive is being compiled on the first IDE bus. The problem is that after the second CPU is launched time outs occur on the SCSI bus. The messages are as follows: (probe:dpt0:0:0:0) : CCB 0xf5526744 - timed out (probe:dpt0:0:0:0) : CCB 0xf5526744 - timed out CCB already completed (probe:dpt0:0:2:0) : CCB 0xf552664c - timed out (probe:dpt0:0:3:0) : CCB 0xf55265d0 - timed out ... (probe:dpt0:0:15:0) : CCB 0xf552607c - timed out ... etc We've installed the 3.0 version on the same machine in single CPU mode without a problem. Can you advise us.
