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. Jonathan [1] http://bugs.debian.org/622325
