I reciently bought a couple Tekram SCSI cards. One was a DC-390T, and the other was a DC-390U. ncr0: <ncr 53c875 fast20 wide scsi> rev 0x26 int a irq 10 on pci0.8.0 tekram_amd0: <Tekram DC390(T)/AMD53c974 Fast10 SCSI Adapter> rev 0x10 int a irq 12 on pci0.9.0 and yes, I'm running an old version of FreeBSD, 3.4-R to be exact, but there hasn't been any major changes to the code as far as I can tell from CVS. I'm having problems with the ncr going out to lunch: ncr0: timeout nccb=0xc0d92000 (skip) swap_pager: indefinite wait buffer: device: 0x411, blkno: 6912, size: 32768 ncr0: timeout nccb=0xc10dfc00 (skip) ncr0: timeout nccb=0xc0d92400 (skip) ncr0: timeout nccb=0xc0d92800 (skip) [timeout messages repeate a few hundred times with swap_pager mixed in] ncr0: timeout nccb=0xc0d91800 (skip) swap_pager: I/O error - pagein failed; blkno 27248, size 8192, error 5 vm_fault: pager read error, pid 1432 (dnsserver) pid 1432 (dnsserver), uid 65534: exited on signal 11 (core dumped) swap_pager: I/O error - pagein failed; blkno 27120, size 8192, error 5 vm_fault: pager read error, pid 1433 (dnsserver) pid 1433 (dnsserver), uid 65534: exited on signal 11 (core dumped) swap_pager: I/O error - pagein failed; blkno 7376, size 4096, error 5 panic: pmap_swapin_proc: cannot get upages for proc: 1435 syncing disks... ncr0: timeout nccb=0xc0d92400 (skip) [with another few hundred (over 350) timeout messages] ncr0: timeout nccb=0xc0d8f000 (skip) ncr0: timeout nccb=0xc0d8f200 (skip) 286 286 286 286 286 286 286 286 286 286 286 286 286 286 286 286 286 286 286 286 giving up finally it decides to sync disks (without any reason, I was myself out grabbing lunch) w/o any reason, and left 286 unwritten... I did reduce the tags on one of the four drives attached to the ncr down to 32, and the remaining drives auto dropped themselves to 32.. Any suggestsions? I tried the tekram ncr driver, but that just crashed shortly after it go to multiuser mode.. will I need to upgrade to 4.2-R to get any decient support? Thanks for the help. I would of cc'd who ever is maintaining the ncr driver, but it doesn't look like any specific person is from the cvs logs.. -- John-Mark Gurney Voice: +1 408 975 9651 Cu Networking "Thank God I'm an atheist, that'd just be confusing." -- cmc To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
