ok, deadlock is gone, instead I have EXT3-fs corruption (non data=journal
mode, just ordered) like this:
Dec 3 00:25:39 codeman kernel: EXT3-fs error (device ide0(3,9)):
ext3_free_blocks: Freeing blocks not in datazone - block = 1530182
, count = 1
Dec 3 00:25:39 codeman kernel: Aborting journal on device ide0(3,9).
Dec 3 00:25:39 codeman kernel: ext3_free_blocks: aborting transaction:
