While theres lots of joy in this release, the network drivers seem to be trouble. I have a pci network card with a DEC tulip driver that fails when loaded on a desktop box(worked in 5.0.1). On another laptop computer my hfa384/prism chipset pcmcia wireless card no longer works (worked in 5.0.1). Autodetect failed to find the built in wifi card on another Dell D610 laptop (I think it was found when using 5.0.1, but not too sure). On the bright side I found that a couple of CISCO AIRONET 350 PCMCIA wifi cards from cisco seem to work ok.

The kernel modules for network cards seem to need work in the new kernel.
