Glad you got it working after all.
I admit that I never have USB modules loaded but I also don't know how
this could affect the Kfir driver, especially if it uses different IRQs.

Yes, in the last CVS version (a few weeks ago) I changed the startup
procedure with laoded=1 to include the Altera reset, just not the
microcode loading. Reloading never crashed for me again after that.

I'll have a look at it but I won't get back my PC with Kfir card
before tomorrow. I hope it is just the kernel version ...
