Package: src:linux-2.6
Version: 2.6-32-5
I've got a Windows 2000 VM running and forwarded a Conexant PCI Modem to it.
Windows detected the device just fine and installed the driver for it.
However, when the modem is used to make a call the kernel crashes instantly
and the system needs to be reset.
See log below.
The kernel was self-compiled from debian source using make-kpkg and 'make
oldconfig' from my old kernel (2.6.30+20~bpo50+1 kernel from backports.org).
The reason to switch to 2.6.32 was that kvm in the backports.org kernel did
not support forwarding PCI devices in the first place...
