Thanks. Arnaud, any hints? To summarize:

- Michael Ott reported with Debian kernel 2.6.38-3 (which is closely
based on stable v2.6.38.2):

syslog tell me every few seconds:
i2c i2c-0: mv64xxx: I2C bus locked, block: 1, time_left: 0

- Manuel Roeder reported the same and found that upstream v2.6.38
triggers the problem and v2.6.37.6 does not.

- Roman Mamedov finds the bug present in Debian 3.1.6-1 (which
is closely based on stable v3.1.6) and Debian 2.6.37-2 (based on
stable v2.6.37.2) but not Debian 2.6.37-1 (based on mainline
v2.6.37).

The regression range described above seems a little inconsistent to
me, so maybe there's something more going on.
