I have also a HP 311c (French edition).
Same problem here.
Freeze at b43-pci-bridge.
I test to blacklist b43,b43-pci-bridge and ssb but it does not change anything (maybe less reboot before a succesful one).
But when b43,b43-pci-bridge and ssb are blacklisted, jockey does not detect my graphic card or wireless card.
With a USB Key the boot is also random but with a CD (plug through USB) it works almost all the times.

I test UNR and have the same issue.
