Finally I could get back to this but after reading the thread I figured it might not be necessary to test this. Please let me know ASAP if you want this patch tested as well or it'll take quite a long time (going skiing for a week on Saturday) In any case, I made the two xfs workqueues non-freezable and everything on my quad powermac works again, I also couldn't detect any filesystem correction. I wanted to adapt the BUG_ON(block IO not from suspend code) patch from suspend2 but haven't gotten around to it yet. johannes --=-mtulcmuYQEa/J9wRz5To Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Comment: Johannes Berg (powerbook) iD8DBQBF7LYb/ETPhpq3jKURAnJ2AKCAK+hM7+Lkf7GJ65471DYySCYNFgCgrG+H jSGr6rqxF/UxHaXBfKWJssU= =+oSe -----END PGP SIGNATURE----- --=-mtulcmuYQEa/J9wRz5To--
