Errors with 3C595

[Borries Demeler]

I have seen exactly the same problem on my SMP dual machine with 
the older 2.0.* kernels when APM was enabled in the kernel. The new
2.2.x kernels don't allow APM to be enabled when using SMP.

Make sure to turn off APM in the bios and the kernel, that solved it
(at least for me)
