[Asterisk-Users] X100P panic

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1


I'm experiencing frequent kernel panics when using the X100P card under 
the 2.6.6 Fedora kernel.  I've attached the kernel output to this message 
- - it looks like the IRQ stack is overflowing and trashing some memory, 
causing a series of oopses followed by a complete crash.

I have just hacked the kernel to reenable 8k stacks and will see if I 
still have the same problem under that once it's finished compiling.

Hmm. I had that happen on my newly built MDK2.6 box with a XTDM400. So it 
probably has nothing to do with the card. I have CVS-HEAD-07/07/04-20:09:43

Don't do everything under the sun on one machine.

I'm betting by that module list you had X up, and you have a TV capture
card, maybe even trying to capture video. I bet you where even doing it
on IDE drives. If so, your answer is obvious.

On the chance I am wrong, start unloading those drivers and see if you
can still crash it.

I've confirmed that the stack overflows caused by the X100P driver are 
caused by running it in a 4K-stacks kernel - it works ok with the linuxant 
16K-stacks kernel, even with the CPU under a high load.
