Oops in 2.2.18

[Lawrence Manning]

Hardware is a Intel 440LX, with IDE disks, 96meg of memory, voodoo 2
graphics etc.  Nothing remarkable.

For about 3 days now, it has been oopsing at least once a day.  Each time
the machine eventually locks up in X.  The kernel is a standard 2.2.18
linus kernel with Alsa drivers (version 0.5.10) for the onboard soundcard,
a yamaha opl3-sa2.

I can supply a kernel config if needed.  Some sample oopses follow.  
Could replies be cc:d to me as I'm not on the list.

Cheers,

Lawrence
