For some unknown reason the kernel will thrash the disk happily for a while, then the card (and presumably the SCSI bus) locks tight. Of course the kernel then vanishes into unspeakable places as it can't do any I/O. (the console messages just complain of bus timeouts AFAIR - then the VM pagers starts griping. I don't have DDB compiled in so it just prints `Debugger(aha1542) called'). Next time someone remind me to get a pen and paper out... The access light on the drive stays on (constantly) when this happens, as does the light on the controller. My setup looks like : External SCSI CD <-> card <-> internal drive Both the CDROM & the hard disk are terminated. My friend just has the disk on it's own. Not another piece of hardware or dust exists on his bus. The boot messages from my machine are appended. Can anyone help? Thanks Gary P.S. My friend says Linux doesn't do this on his hardware. I'm not mad enough to try... :-) -- SNIP -- FreeBSD 2.1.0-Development #0: Tue Feb 21 16:56:36 GMT 1995 root@palmer.demon.co.uk:/usr/src/sys/compile/WESTHILL CPU: i486DX (486-class CPU) real memory = 8257536 (2016 pages) avail memory = 7135232 (1742 pages) Probing for devices on the ISA bus: sc0 at 0x60-0x6f irq 1 on motherboard sc0: VGA color <16 virtual consoles, flags=0x0> ed2 at 0x300-0x31f irq 10 maddr 0xcc000 msize 16384 on isa ed2: address 00:00:c0:5c:46:8e, type WD8013EPC (16 bit) bpf: ed2 attached sio0 at 0x3f8-0x3ff irq 4 on isa sio0: type 16450 sio1 at 0x2f8-0x2ff irq 3 on isa sio1: type 16450 lpt0 at 0x278-0x27f irq 7 on isa lpt0: Interrupt-driven port lp0: TCP/IP capable interface fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa fdc0: (NEC 72065B) [0: fd0: 1.44MB 3.5in] wdc0 at 0x1f0-0x1f7 irq 14 on isa wdc0: unit 0 (wd0): <94354-230> wd0: 201MB (412128 total sec), 1272 cyl, 9 head, 36 sec, bytes/sec 512 aha0 is a 154xCF-2.01-VB.0: enabling mailbox and residuals aha0: reading board settings, dma=5 int=11 (bus speed defaulted) aha0 at 0x330-0x333 irq 11 drq 5 on isa aha0 waiting for scsi devices to settle aha0 targ 0 lun 0: type 0(direct) fixed SCSI2 aha0 targ 0 lun 0: sd0: 1013MB (2074880 total sec), 2756 cyl, 8 head, 94 sec, bytes/sec 512 aha0 targ 6 lun 0: type 5(readonly) removable SCSI2 aha0 targ 6 lun 0: cd0: cd present.[208702 x 2048 byte records] npx0 on motherboard npx0: INT 16 interface bpf: lo0 attached bpf: sl0 attached
