So I decided whether anything has change in this situation lately (Debian/testing, 2.6.11-rc3-pa3, 32bit, gcc-3.4.4). I tried a noname Silicon Image Sil680 based IDE controller and a Promise Ultra100 Tx2 (I compiled all IDE stuff and IDE drivers as modules, so I could more easily test it). I didn't have any luck getting the IDE controller to work, but at least now I got much different error messages than I used to get (months ago). Maybe this might help you to locate the problem: kernel: Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2 kernel: ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx kernel: PDC20268: IDE controller at PCI slot 0000:01:04.0 kernel: PCI: 0000:01:04.0 has unsupported PM cap regs version (1) kernel: PDC20268: chipset revision 2 kernel: PDC20268: ROM enabled at 0xf4a00000 kernel: PDC20268: 100%% native mode on irq 21 kernel: ide0: BM-DMA at 0x12100-0x12107, BIOS settings: hda:pio, hdb:pio kernel: ide1: BM-DMA at 0x12108-0x1210f, BIOS settings: hdc:pio, hdd:pio kernel: Probing IDE interface ide0... kernel: hda: ST3120022A, ATA DISK drive kernel: ide0 at 0x12500-0x12507,0x12402 on irq 21 kernel: irq 21: nobody cared! kernel: Backtrace: kernel: [<10143de4>] __report_bad_irq+0x34/0xac kernel: [<10143f4c>] note_interrupt+0xbc/0xf4 kernel: [<101438d0>] __do_IRQ+0x17c/0x190 kernel: [<101072fc>] do_cpu_irq_mask+0xa8/0xe4 kernel: [<1010c068>] intr_return+0x0/0x14 kernel: handlers: kernel: [<002ed640>] (ide_intr+0x0/0x290 [ide_core]) kernel: Disabling IRQ #21 kernel: Probing IDE interface ide1... kernel: hdc: PLEXTOR DVDR PX-716A, ATAPI CD/DVD-ROM drive kernel: ide1 at 0x12300-0x12307,0x12202 on irq 21 This particular message showed up when I tried the Promise card with the pdc202xx_new driver in a 33MHz slot. Exactly the same backtrace occurs when I put the card in a 66MHz slot and also when I tried the Silicon Image card with the siimage driver (33MHz). As you can see from the log, the hdd and the DVD burner are correctly detected, but I cannot access them; a 'mount /dev/hda ...' or a 'cat /dev/hda' results in 'cannot open /dev/hda'. (The Promise card with the pdc202xx_old driver does load, but doesn't detect anything nor does anything show up in the logs) Thanks a lot in advance, Max _______________________________________________ parisc-linux mailing list parisc-linux@lists.parisc-linux.org http://lists.parisc-linux.org/mailman/listinfo/parisc-linux
