Tyan S2464 (K7 SMP) + EMU10K1 hardlocks

Tyan S2464 (K7 SMP) + EMU10K1 hardlocks

[Chris Fuller]

I've established by now that the problem is definitely not with the
Linux kernel, but there was a discussion here about this very issue last
August, and I haven't found a reference to it anywhere else, so please
help if you can. :)

I'm seeing hardlocks in various 2.4 kernels (10, 18, 19-pre8, all SMP):
  mobo=Tyan S2464 (K7 Thunderbird) SMP
  NVidia GeForce4 AGP
  SBLive! Platinum 5.1
  Two 40G IDE hard drives

I can reproduce at will (Unreal Tournament aggrivates it), but it can
happen at any time.  It even locked up in the BIOS Setup(!) at one
point.  Last August, Eric S. Raymond started these threads which seem to
be the same problem:
  Hang problem on Tyan K7 Thunder resolved -- SB Live! heads-up
  S2464 (K7 Thunder) hangs -- some lessons learned

First trying the things I usually try to regain system stability, then
based on what I learned from the above threads, I have found that even
doing *all* of the following does not correct the issue for me:
  nosmp or pulled 2nd CPU
  ide=nodma
  disableapic or noapic
  apm=off
  additional cooling
  memory swap
  video card swap, both pci and agp, both 3dfx and nvidia
  "Use PCI Interrupt Entries in MP Table" -> "yes"
  No emu10k1 driver at all

Yanking the sound card completely out of the machine makes the hardlock
go away, but the card works flawlessly in my Abit K7 system.

Am I forgetting to try something?

Does anybody have any further advice on this?

Does anyone know if it's the motherboard or the card that's actually
doing something wrong, so I can know whom to yell at and/or avoid in the
future?

I can't even find info on this mobo.  Every hit Google returned was a link
to a thread on lkml :)  Does it have a VIA chipset by any chance?

There is a known lonstanding incompatibility between the SoundBlaster
Live! series and the VIA VT82C686B southbridge.  You can fix it by messing
with your BIOS, but I wasn't brave enough to try that.  You can get more
info from www.viahardware.com I think (it won't load properly on this
computer so I can't give an exact link).

Creative Labs warns that it's sblive series of cards aren't compatible 
with SMP systems.  Though i've had the S2460 motherboard and the only 
trouble i have had was that EAX didn't work properly.  A friend of mine 
has an sblive with a dual celeron and he also has had this problem of 
deadlocks with the SBLive.  The audigy however is fully compatible.


Also, make sure you have an adequate power supply.

On Linux at least I've never had a problem with the SB Live since the
SMP bugs in earlier 2.4 trees got fixed (and they were kernel bugs). I
can well believe the SB emulation magic doesn't work with old games in
SMP mode but we don't drive it in any emulation mode nor need to

It may be that there software, livewear, is buggy on SMP systems. Again 
it's cryptic, they do not state if it is the board or only the driver.

Like i said, i've been running windowsXP/linux2.5.20 on a dual athlon 
motherboard (Tyan S2460 before it busted, now i have an Asus A7M-266) 
and both worked fine.  My friend's dual celeron didn't take the sblive 
too nicley.

It could also be a power supply issue.  Maby the sound card is the drop 
that spills the glass.
