VIA IDE controller strangeness (2.4.0-test12/test13-pre5)
---(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.

To: should be fine as well, I assume.

Could you report the chip set type and revision? Quote the corresponding parts from the "lspci -v" output, please. I've been using PC Chips main boards with VIA chip sets without IDE difficulties ever since I bought one of those in fall 1998. (VIA Apollo MVP3 AGP, VT82C598 + VT82C586 north+south bridges), both PC Chips M577 and Tyan Trinity S1590S. -

Alrighty then (this is output from lspci -v running under 2.2.18pre21):
-- BEGIN OUTPUT --
...
00:07.0 ISA bridge: VIA Technologies, Inc. VT82C586/A/B PCI-to-ISA

-- END OUTPUT --
Now...one thing I noticed is that Linux is trying to find this IDE interface through PCI and it reports it on 00:07.1 during -test12 and -test13-pre5 boot up (I can't get a dmesg output for you 'cause it never boots...just keeps complaining about hdb: lost interrupt), but the IDE controller seems to be an ISA device (unless I've read this wrong). In case I'm configuring something wrong, I've pasted the IDE .config portions here:
CONFIG_BLK_DEV_IDEPCI=yCONFIG_IDEPCI_SHARE_IRQ=yCONFIG_BLK_DEV_IDEDMA_PCI=yCONFIG_IDEDMA_PCI_AUTO=yCONFIG_BLK_DEV_IDEDMA=y
ONFIG_BLK_DEV_VIA82CXXX=yCONFIG_IDEDMA_AUTO=yCONFIG_BLK_DEV_IDE_MODES=y
Hope this stuff helps you guys out.
If somebody wants to tell me a better way to get nvi to wrap lines at 75 chars (other than hitting enter when I think it has to be hit), you could e-mail me (don't bother sending it to the list).
CC replies please. I don't subscribe to linux-kernel. Sorry.
