Keefe" Subject: Re: timeouts with adaptec 1742 Cc: freebsd-scsi@FreeBSD.ORG Sender: owner-freebsd-scsi@FreeBSD.ORG X-Loop: FreeBSD.org Precedence: bulk I have been experimenting with this problem some more and had a few questions. I have been running 2.1.7.1. I noticed that there were some modifications to the adaptec 1742 device driver code. Do you think that these changes could have anything to do with the timeout problem that I am having? I did try recompiling 2.1.7.1 with some of the changes, but I only subsitituted some of the files. I have tried experimenting with many of the mode page settings with no success. However, if you have any suggestions, I am happy to try. I am able to create a new file system on the 2.1GB seagate drive. However, when I run FSCK, the controller hangs. If I run FSCK in the debugger and slow down the execution (set a breakpoint and repeatedly continue) I can get through the FSCK completely. I have also modified FSCK to insert delays often enough to avoid hanging. I thought perhaps by placing delays in the correct places I may be able to keep the controller from hanging. I don't think its a good longterm solution, but I thought I might learn something about the problem. As you can probably tell, I am quite desperate to get this to work. If you have any advice as to how to proceed, I would be grateful. Tom Keefe Information about the system: ASUS T2P4D Dual CPU ISA/EISA/PCI motherboard 64MB EDO RAM 200MHZ Pentium Built-in IDE disk adapter (not used - disabled) Adaptec 1742A (standard mode) Seagate 3390 (330 MB SCSI disk - unterminated) Seagate st32151n (2.1GB SCSI disk - terminated - power from bus) NE2000 Compatible ethernet card - IRQ 10 - 0x300 FreeBSD 2.1.7.1 Information about problem: Cannot install FreeBSD onto st32151n. Can install onto 3390 disk on same adapter. Am able to FDISK, Disklabel and create file system on st32151n. Can copy information to new filesystem but I sometines hang the controller when copying information from the new filesystem. When I try to FSCK a partition on st32151n drive the adapter hangs with timeout.
