---(CC answer please)---
I'm having a strange problem with my IDE controller. I believe (and that's what
Windows and the m/b manufaturer -- PC Chips -- say) that I have a VIA PCI BusMaster
IDE controller, and I've had some strange history with it. I've asked many people
before on various help services, and I was able to fix my problem with the 2.2 series,
but now my fix does not work.
THE PROBLEM:
------------
Ever since the 2.2 kernel series (I remeber this working properly in 2.0.36, without
the conflicts), I would get hdc: lost interrupt during boot up, and my system would
take bloody ages to boot up and load a CD. I tracked it down to a strange IRQ
conflict in which Linux would try to assign both the primary and secondary IDE
channels IRQ 14, causing IRQ conflicts galore. I was able to fix this by giving the
kernel
ide1=0x170,0x376,15
at boot time. This has worked for 2.2.12-.17 and Alan's 2.2.18pre21 (I haven't
compiled the official 2.2.18 yet, but I'm sure it will work).
I wanted to try the new 2.4.0-test series, and the first I tried was -test11, and from
what I recall (other things weren't working properly then), this fix still worked, but
now, with -test12, I am now getting the following error repeated for a very long time
(then I reboot) with the same parameters:
ide_dmaproc: chipset supported ide_dma_lostirq func only: 13
hdb: lost interrupt
Also, I get "spurious 8259A interrupt: IRQ 7" if I leave it for a while. I tried
-test13-pre5 on somebody on #KernelNewbies' suggestion, and I get the same error.
Scrolling up, I see that the kernel messages show that ide0 is on IRQ 14 and ide1 is
on 15. I noticed that hda is using DMA, and hdb is using UDMA33, but I don't believe
that that is the problem.
THE QUESTION:
-------------
How do I fix this, or is it a (un)known problem in the newer development versions? If
you have the answer, could you please CC me as well for I don't subscribe to this
mailing list (sorry!). Thanks a bunch.
