I think that this patch is already commited to -STABLE, and so i rebuilt my kernel and world again today, but the problem is still here. The machine deadlocked very hard this time, it even stopped responding to ping requests. This time i was rsyncing this monstrous imap mailbox (about 8G), and ran several times "du -sh Maildir" on the target machine, everything looked ok, and then i decided to run "iostat" and when i pressed enter the shell freezed. I will try to setup debugger on the serial console tomorrow to see if i can get some useful info. I'm open to suggestions on how to debug this :) Thanks, Niki -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFD158JHNAJ/fLbfrkRAspmAJ9VJdqMiVljckJUtgipZx1i/UTh1QCcCV+I K2qgeScOMZGz4fxMFnvnE9Q= =cOPx -----END PGP SIGNATURE-----
