Re: DISCOVERED! Cause of Athlon/VIA KX133 Instability
I don't know if it's the motherboard, but I've got a KT7A-RAID, and I haven't been able to run any 2.4.x that I've tried. I was worried, because this board also has new RAM, but 2.2.x doesn't have any problems at all. I've tried: 2.4.2 2.4.3 2.4.3-ac9 2.4.3-ac11 Someone else mentioned stability problems with nVida and AGP, which I'm also using. It's true that I've only experienced lockups under X. Things I haven't tried, but should (and will, once finals are over): 2.4.x, unoptimised 2.4.x, optimised, disable AGP I'm running Debian unstable (but it's not unstable with 2.2.x :) -- --Ray - Sotto la panca la capra crepa sopra la panca la capra campa - 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/

But I like to point out that on my Athlon kernel 2.4.3 is working fine. The first kernel I face problems is 2.4.3-ac7. I also know that the problem occurs of kernel 2.4.4. That might help to find the problem. - 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/

Re: DISCOVERED! Cause of Athlon/VIA KX133 Instability
>Maybe, but the IWILL board is the only one we've heard about problems with. I have also stability problems with an ASUS A7V133. I already have the 1004-d2 bios which should fix the VIA IDE problems. But my hard drives are connected to the promise controller of the board. Only 2 CD-drives are on teh VIA-Chip. I am quite sure that my problem was introduced with 2.4.3-ac7, because, the board is rock solid up to kernel 2.4.3-ac6 or with the Madrake 8 kernel. But If I try to put some load on 2.4.3-ac7 or above I get lock ups. Even the magic sysrq does not work. No matter if compiled for athlon Pentium II or 586. No matter if I use the mandrake 8 gcc 2.96 or a self compiled gcc 2.95.3. The problem also occurs on kernel 2.4.4. Bytheway there is a thread called "ABit KT7A-RAIN random lock ups " It might be related to one of the Athlon/VIA problems. greetings Christian - 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/

Maybe, but the IWILL board is the only one we've heard about problems with. The Abit KT7A (which also has the KT133A chipset and is otherwise identical to the KT7) would appear to run smoothly, although I don't actually *have* one of those. Probably the Windows drivers turn off some feature of the IWILL board which is known to be flaky. I suggest setting *everything* in the BIOS to the "most conservative" settings and seeing if the problem persists. If so, then it can't be a hardware-speed-limitation problem, and there's clearly something we have to turn off "manually". Also, try running memtest86 and see if that is capable of triggering the problem. -- from: Jonathan "Chromatix" Morton mail: [EMAIL PROTECTED] (not for attachments) big-mail: [EMAIL PROTECTED] uni-mail: [EMAIL PROTECTED] The key to knowledge is not to rely on people to teach you it.

Re: DISCOVERED! Cause of Athlon/VIA KX133 Instability
Thanks moses -- this is the instability that I have as well. I tried compiling on 1/2 of the k7 optimized mmx routines. So far, running with JUST the fast_clear_page using k7 streaming (and not fast_copy_page), the system is still stable. I'll try adding fast_copy _page, but I think that's where our problems lie (of course I could be full of crap, too). --S Moses McKnight wrote: > > Mark Hahn wrote: > > >> Actually, I think there are 2 problems that have been discussed -- the > >>disk corruption and a general instability resulting in oops'es at > >>various points shortly after boot up. > >> > > > > I don't see this. specifically, there were scattered reports > > of a via-ide problem a few months ago; this is the issue that's > > gotten some press, and for which Alan has a fix. and there are reports > > of via-smp problems at boot (which go away with noapic).

This is with the board and RAM pushed as fast as it will go without actually overclocking anything... and yes, I do have Athlon/K7 optimisations turned on in my kernel (2.4.3). Out of interest, what FSB are you using for your machine? I understand the difference between the KT133 and the KT133A is that the latter supports a 266MHz FSB for the Athlon rather than 200MHz. Since your CPU is running cool, I doubt you've managed to accidentally o/c it, but nevertheless this is a possibility... The 266MHz FSB does require considerably higher standards in board construction though, so it could be that IWILL have managed to do a shoddy job on that end. -- from: Jonathan "Chromatix" Morton mail: [EMAIL PROTECTED] (not for attachments) big-mail: [EMAIL PROTECTED] uni-mail: [EMAIL PROTECTED] The key to knowledge is not to rely on people to teach you it.

When I reported my problem a couple weeks back another fellow said he and several others on the list had the same problem, and as far as I can tell it is *only* with the IWILL boards.

I don't see this. specifically, there were scattered reports of a via-ide problem a few months ago; this is the issue that's gotten some press, and for which Alan has a fix. and there are reports of via-smp problems at boot (which go away with noapic). I see no reports of the kind of general instability you're talking about. and all the via-users I've heard of have no such stability problems - me included (kt133/duron). the only general issue is that kx133 systems seem to be difficult to configure for stability. ugly things like tweaking Vio. there's no implication that has anything to do with Linux, though. > > My memory system jas been set up very conservitavely and has been > rock solid in my other board (ka7), so I doubt it's that, but I > sure am happy to try a few more cominations of bios settings.

Hi :) And that's exactly what I did :)... I found that ONLY the combination of USE_3DNOW and forcing the athlon mmx stuff in (by doing #if 1 in mmx.c) results in this wackiness. I should alos repeat that I *DO* see that wierdness you described with 3DNOW (in my case, it was that kde locks up when i try to do something). This is damn weird... Who thought channging motherboards would result in this? The other thing i was gunna try is to dump my chipset registers using WPCREDIT and WPCRSET and compare them with other people on this list who have been having the problem.

DISCOVERED! Cause of Athlon/VIA KX133 Instability
Ok, so the subject is an attention-getter :). Peep this, homies: Hi, I've been doing some research, trying to figure out why the VIA/Athlon is exhibiting weird behavior under K7 optimizations. The jist of my research is that compiling a kernel for ANY CPU with the Athlon MMX optimization *AND* 3DNOW results in massive amounts of oops'es and total system instability. The following is what I've tried: [1] Selected Athlon as CPU in .config, then commenting out (#if 0) the mmx code optimized for the athlon (as was stated is the only main k7 opt). The resulting kernel is stable. enabling/disabling other options have no effect on stability. [2] Experimented with choosing K6-(III) optimized kernel, but modifying the arch/i386/config.in to sequentially add to the K6 section all the options in the K7 section (i.e. GOOD_APIC, USE_3DNOW, L1_CACHE_SHIFT difference, and PGE). So far, the only anomolay I've found is that when I add USE_3DNOW to the K6 section and reboot, KDE hangs when I click on any button in my launch bar (vanilla KDE 2.0). It does NOT hang the system, though. Restarting Xwindows does not help, but changing the WM to TWM allows me to run netscape (which was one of the buttons that hund X in KDE in the launch bar). Weird, right? Enabling paging extensions (CONFIG_X86_PGE) appears to have no effect on stability. [3] When I add 3DNOW to any option in [2] w/ the Athlon MMX opt, the instability is evident after root is mounted and startup scripts begin executing. Sometimes the system can make it through other times it cannot.
