I managed to get some information out of the tablet with perf. It seems to be a driver problem (bcm4330), but I don't have any debug symbols to see any more info. Anyone got any?

Code:
# Overhead          Command                     Shared Object
# ........  ...............  ................................  ...........................................
#
    86.33%          swapper  [bcm4330]                         [k] 0xffffffff820163a6
