Please read the pages at: http://home.tiscalinet.de/au-ja/review-kt133a-1-en.html (and especially click on "Bugfix for everybody"); this URL is in the code. You will note that it is explicitly stated that this fix is NOT meant for any other Northbridge than VIA. So, in short, if there is no BIOS update available for your board, you're going to have to some more research. The PCI registers that are configured could have a totally different (and even dangerous) effect on your configuration. -- charl p. botha | computer graphics and cad/cam http://cpbotha.net/ | http://www.cg.its.tudelft.nl/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

That's the first version I sent which was admittedly broken. About 20
minutes later I sent the fixed version (mail with subject: "Re: 2.4.4 Sound
corruption [PATCH] NEW, ignore previous patch"). In case you can't find
this, I've re-attached the patch.

VIA has recognised it, and motherboard vendors are already starting to release updated BIOSes that sport the required settings (e.g. Abit, see http://www.viahardware.com/faq/kt7/faqbios.html). I'm just afraid if the kernel starts disabling IDE DMA on certain of these setups, there'll have to be checks (in the kernel) for possible future updated BIOSes as well (else we disable IDE DMA where it's not necessary). Selective application of the fix (as in my patch) does no harm on the known combinations though.

Re: pci/quirks.c - VIA PCI latency in 2.4.4
I should probably clarify. The fix is *only* valid for the VIA VT8363 host to pci bridge, therefore the test for the 686B south bridge only gets done if a 8363 is found. No fix is known for intel pci-to-host bridges with the 686B south bridge, and in the case of the AMD-761 chipset, there are certain BIOS settings you can change.

Please IGNORE the previous patch, it was faulty (I blame it on the time of

Re: 2.4.4 Sound corruption [FIXED]
I have found the problem. The VIA latency patch in linux/drivers/pci/quirks.c at line 92 (quirk_vialatency()) should NOT be applied for the VIA VT82C686A (only for the 686B). On my machine (at least) it's causing problems (as documented below) and this bug (along with fix) is only applicable on the 686B southbridge. I have removed this code and everything is now fine on my system. The problem is that the 686A and 686B have the same PCI IDs, else I would have submitted a patch. Should I send this information anywhere else to make sure it gets applied in new kernels? On Mon, Apr 30, 2001 at 01:29:15AM +0200, Charl P.

Re: 2.4.4 Sound corruption
2.4.4 has broken sound here in a very strange way. I have a debian testing system, Abit KT7 (thus VIA KT133 chipset) and SB PC128 (es1371-based) sound card. Up until 2.4.3 everything was fine. Now, however, when I send _anything_ to /dev/dsp, I get continuous high-pitched beeping (nothing remotely resembling what the sound card should be doing). The strange thing is that when I cause hard disk activity (find / -name "*") the correct sound is produced in time with hard disc accesses (I have tried this with DMA enabled and disabled on the drive, same results). Also, when I switch desktops (icewm, XFree86 4.0.2, Nvidia 0.9.767 drivers) the correct sound is (very) momentarily produced (almost non-detectibly). After these periods of lucidity, the sound card returns to its high-pitched cacophony. I have attached copies of both /proc/interrupts and /proc/pci. If anyone requires more information, please say the word. I am not subscribed to this list.
