Xine causes kernel panic

[Brendon and Wendy]

All,

With some help from Kris Kennaway, I've now done some more poking
around. The reason that Xine "locks the machine hard" is that it is
causing a 100% repeatable, panic that I can trigger with a UP or MP
kernel with or without the NVIDIA GLX drivers in kernel.

The backtrace looks like:

dsp_clone(0, e072095f, 4, e07208d0, c197af0c) dsp_clone + 0x136
devfs_lookup(e07209c8, 1, 0, c46be930, c4) devfs_lookup + 0x302
lookup + 0x24e
namei + 0x24e

vn_open + 0x33
kern_open + 0xce

Xint0x80_syscall() Xint0x80_syscall + 0x1d

Registers:

-------------------------------------------------

Hardware is a SB Live, Intel i860, dual Xeon. This fault has been
introduced since Christmas I think.

Hope this helps.

As usual I'm happy to perform tests, poke and prod etc etc.
