I could use some help (no, not that kind). I recently replaced my ASUS
PVI-486SP3 motherboard (SiS 85C496/497 chip set) and AMD 5x86 CPU with a
no-name motherboard ("P5TVX-AT," Intel Triton II chip set) and Pentium
CPU. My SCSI host adapter doesn't work with the new board.
# insmod aha1542
/lib/modules/2.1.40/scsi/aha1542.o: init_module: Device or resource busy
I tried adding some printk statements to aha1542.c, and found that the
driver usually gets that error message as it's doing this:
/* Quick and dirty test for presence of the card. */
if(inb(STATUS(bse)) == 0xff) return 0;
although one time it apparently got past that:
May 20 18:15:29 topside kernel: aha1542.c: doing quick and dirty test.
May 20 18:15:29 topside kernel: aha1542.c: quick and dirty test returned
true, resetting interrupts.
May 20 18:15:29 topside kernel: aha1542.c: done resetting interrupts,
writing control.
May 20 18:15:29 topside kernel: aha1542.c: waiting.
May 20 18:15:29 topside kernel: aha1542.c: setting debug level to 1.
May 20 18:15:29 topside kernel: aha1542.c: doing quick and dirty test.
I've tried compiling the driver into the kernel proper, rather than as a
module. It just reported:
scsi: 0 hosts.
scsi : detected total.
I tried three different versions of the kernel from {2.1.40, pre-2.0.31,
2.0.29, 2.1.29} with the same result (only as a module).
My card is set to use 0x134, DMA 6 and IRQ 10; the BIOS is enabled and DIP
switches are set to 01011101. In the CMOS setup, I marked IRQ 10 and DMA
6 as "legacy ISA." I also have:
- SoundBlaster 32 PnP
- Realtek PCI NE2000 clone
- Cirrus Logic DG5424 ISA video card (I'd been using a DG5426-based VESA
card before)
- internal modem
- serial mouse running off the motherboard's ALI M5112
- IDE hard drives
The board has an ALI M5112 chip providing built-in ports:
- USB (disabled)
- PS/2 (disabled)
- dual IDE (both working)
- parallel (working)
- dual serial (one working, one disabled)
