Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I've got a FreeBSD 3.4 system with a 2940U2W and SCSI 3 hard drive attached to the A channel. This setup runs great until I attach a CDRW drive (YAMAHA CRW4416S) to channel B. The 2nd device causes it to hang just before the login prompt. The Adaptec BIOS sees the CDRW and maps it to ID#4 but even with the trasfer rate set to 5MBPS the system will hang: fdc0: FIFO enabled, 8 bytes threshold fd0: 1.44MB 3.5in wdreset: error1: 0x25 wdreset: error1: 0x25 wdc0 not found at 0x1f0 lnc0 not found at 0x280 vga0 at 0x3b0-0x3df maddr 0xa0000 msize 131072 on isa npx0 on motherboard npx0: INT 16 interface (probe4:ahc0:0:4:0): SCB 0xa - timed out in command phase, SEQADDR == 0x15d (probe4:ahc0:0:4:0): BDR message in message buffer (probe4:ahc0:0:4:0): SCB 0xa - timed out in command phase, SEQADDR == 0x15d (probe4:ahc0:0:4:0): no longer in timeout, status = 34b ahc0: Issued Channel A Bus Reset. 11 SCBs aborted Has anyone come across this and, if so, is there a fix? -- Roger Marquis Roble Systems Consulting http://www.roble.com/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
