Mattingly) Newsgroups: comp.unix.bsd.freebsd.misc Subject: Misc questions (sound card; scsi cdrom) Date: 11 Oct 1996 00:27:10 GMT Organization: North Carolina State University Lines: 40 Message-ID: <53k48u$j2@taco.cc.ncsu.edu> NNTP-Posting-Host: heli-fishing.eos.ncsu.edu X-Newsreader: TIN [UNIX 1.3 950824BETA PL0] Occasionally I get the following message showing up: Oct 9 22:40:59 cam-home /kernel: Sound: DMA timed out - IRQ/DRQ config error? I'm trying to figure out why this is, since under *shudder* Win95, nothing shows a conflict nor error. Here's some relevant information: Oct 10 20:01:28 cam-home /kernel: ahc0 <Adaptec 2940 SCSI host adapter> rev 3 in t a irq 11 on pci0:14 Oct 10 20:01:34 cam-home /kernel: sio0 at 0x3f8-0x3ff irq 4 on isa Oct 10 20:01:34 cam-home /kernel: sio1 at 0x2f8-0x2ff irq 3 on isa Oct 10 20:01:34 cam-home /kernel: lpt0 at 0x378-0x37f irq 7 on isa Oct 10 20:01:34 cam-home /kernel: fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa Oct 10 20:01:35 cam-home /kernel: sb0 at 0x220 irq 5 drq 1 on isa Oct 10 20:01:35 cam-home /kernel: sb0: <SoundBlaster 16 4.13> Oct 10 20:01:35 cam-home /kernel: sbxvi0 at 0x0 drq 5 on isa Oct 10 20:01:35 cam-home /kernel: sbxvo0: <SoundBlaster 16 4.13> Oct 10 20:01:35 cam-home /kernel: sbmidi0 at 0x330 on isa Oct 10 20:01:35 cam-home /kernel: <SoundBlaster MPU-401> I can't recall what did this, but I believe it was while trying to record from /dev/audio. The other question is what can I do to resolve this 'annoyance'? Oct 10 20:01:29 cam-home /kernel: cd1(ahc0:6:X): ILLEGAL REQUEST asc:25,0 Logical unit not supported Where X goes from 1 to 6. What is causing the kernel to probe that cdrom on each lun at that id? (A jumper on the cdrom maybe?)
