| |
I am seeing "lost interrupt" during kernel init, immediately after the drive is probed.
The system boots under 2.2.x, using the kernel supplied with the current stable Debian release. I have not yet tried it with 2.4.x(I had to transfer 2.6.x as split on floppies as the network device won't work with 2.2.x).
Data is copied by hand from the monitor, so accuracy not guaranteed(but I think its correct)...
Relevant lspci line, after booting under 2.2.x... 00:1f.1 IDE interface: Intel Corp. 82820 820 (Camino 2) Chipset IDE U100 (rev 05)
We have had problems with these devices(ACS7500, a transparent IDE RAID controller from Accusys) on other boards where the BIOS wouldn't boot them, so they may be doing something weird with the standards. The BIOS on this board can allow the system to boot correctly off this device.
Relevant part of the output on bootup... hda: Accusys ACS7500 C5VL, ATA DISK drive ide0 at 0x1f0-0x1f7, 0x3f6 on irq 14 hdc: LG CD-ROM CRD-8522B, ATAPI CD/DVD-ROM drive ide1 at 0x170-0x177,0x376 on irq 15 hda: 234441648 sectors(120034 MB) w/2048 KiB Cache, CHS=16383/255/63 hda:<4>hda: lost interrupt lost interrupt lost interrupt (continues forever)
I have tried (without success) enabling all workarounds in the kernel config, disabling APIC(noapic on command line, this is a single P4), disconnecting the CDROM from the secondary IDE, swapping the disk onto the secondary IDE, disabling DMA-by-default in the kernel config, disabling DMA in the BIOS setup, setting the PIO mode in the BIOS setup to 0, and trying the old driver on the primary interface(which failed because the device has too many cylinders).
Has anyone else seen this sort of problem? (Sorry if this is a known issue, I couldn't find anything that seemed to be the same in the archives). Has anyone got an ACS7500 running under 2.6.0, or 2.4.x for any recent kernel?
If you anyone needs any more info I should be able to get it, but remember I can't actually boot into 2.6.0 only the 2.2.x kernel. -- Yours sincerely, Andrew
