Public bug reported:
Receiving this mysterious "serious kernel error" over and over since
installing. Natty daily build, x86_64 Mac version, installing on a stock
15" MacBookPro 6,2.
dmesg shows some warnings related to the mac80211 driver, which may or
may not be what this is. No clear information about it was shown to me
by the automatic bug reporting tool, but I had to try about 10 times
before one got through.
