irq sharing leads to system freeze

[Chris Mailer]

Hello,

Im using an old Evo N600c laptop with rtw0 pcmcia cardbus lancard.
Utilizing the lancard (e.g. through netstart) while playing sound as
well as playing sound while beeing online leads to an immediate system
freeze.
It seems that sound and network share IRQ 11.
I tried to change the IRQ settings using config(8), which, however,
doesn't seem to have any effect since the IRQs appear to not been set
at that early state of boot.
Here is my dmesg output: http://sprunge.us/KRAa
Thanks,

 Chris

What you are trying to do is insane, wrong, and entirely unsupported.

Find the bug. :) Interrupt sharing should not be a problem. It indicates a
some other problem exists, and that's the one that should be fixed.

This is not necessarily easy, but half-hearted workarounds aren't any better.
