No, it did not. This time I tried 2.6.5-rc3-mm4. Seems the patch was already applied in this release. modem_run did not lock (disk sleep state) in the same place, but it locked after writing synchronization succeded to system log. It seems that there is no kernel-stack-for-process-in-proc option in mm (Andrew, can you add it?), so there is no callstack.
but still thanks for your help and looking for next :)
