[Emu10k1-devel] emu10k1 v0.18 SMP crash

[<Na...@un...>]

Greetings...

I get the following when trying to capture audio:

That's in the "really not good" category, as far as I'm concerned.  This
happens with v0.18 of the emu10k1 driver.  It happens under 2.4.17 (with
v0.18 installed from source) and 2.4.18 (with v0.18 included).  It
happens with at least *two* pieces of video capture software (mp1e and
ffmpeg).

It does *not* happen with either piece of software using v0.16 under
2.4.17.


Here's the relevant output from /proc/pci:
  Bus  0, device   9, function  0:
    Multimedia audio controller: Creative Labs SB Live! EMU10k1 (rev 8).
      IRQ 12.
      Master Capable.  Latency=32.  Min Gnt=2.Max Lat=20.
      I/O at 0xcc00 [0xcc1f].
  Bus  0, device   9, function  1:
    Input device controller: Creative Labs SB Live! (rev 8).
      Master Capable.  Latency=32.
      I/O at 0xd000 [0xd007].
  Bus  0, device  11, function  0:
    Multimedia video controller: Brooktree Corporation Bt848 TV with DMA push (rev 18).
      IRQ 5.
      Master Capable.  Latency=32.  Min Gnt=16.Max Lat=40.
      Prefetchable 32 bit memory at 0xdb002000 [0xdb002fff].

Here's lspci, if that's more readable:
00:09.0 Multimedia audio controller: Creative Labs SB Live! EMU10000 (rev 08)
00:09.1 Input device controller: Creative Labs SB Live! (rev 08)
00:0b.0 Multimedia video controller: Brooktree Corporation Bt848 TV with DMA push (rev 12)

The card in question is an SBLive! Value.  The machine is a dual Pentium
III 700 (Abit VP6, not overclocked).  The TV capture card (probably not
relevant) is a Zoltrix TV-Max.

Is there any other information I can provide to help trace this thing?
Should I steal the emu10k1 directory from 2.4.17 and compile v0.16
agains 2.4.18 in the meantime?

Thanks,
