Most recent kernel where this bug did not occur: 2.6.11
Distribution:Gentoo  ( using Gentoo kernels) 
Hardware Environment: Amd Athlon 2500+
Software Environment
Problem Description:

When loading "winecfg" or other wine system, while the snd-mpu401-uart module is
loaded,  the kernel will completely hang.

The card in question is a Hoontech 4DWaveNX ( Trident chipset ) , and this has
been present in every kernel I've tried since 2.6.11.* 

I haven't been able to run a kdb session over serial console(I simply don't have
the cable), or get a decent oops out of it on a console.  However an Alt+SysRQ+P
tells me its in the snd_mpu401_uart_input_trigger+0xcc/0x1b0, and a simple
brute-force test (unload the modules and wipe them from disk) proved the case by
not crashing.



Steps to reproduce:

start "winecfg"
