Stubborn as I am, I decided to give 2.6.14 another shot for it. Following a recommendation found in the above mentioned thread, I tried the patch from=20 http://iphitus.loudas.com/archck.php this time, which includes the latest reiser4 from mm. Unfortunately I once more hit the wall and was forced to go back to 2.6.11 (including another --build-fs run to regain compatibility with the old but working reiser4 drivers). I wish there was a mount option to exclude the new extensions so I can test new kernels without losing half a day for fscking when things get whacky. This time suspend seemingly works without reiser4 processes freaking out. But now it looks like any time any mmapped file is synced to a reiser4 partition, the process who tries to do that will freeze forever. In addition, any process trying to access the open mmapped file afterwards will freeze forever as well. I created a screenshot of an strace running while this happened. Find it at http://fionn.de/reiser4again.jpg Of course, tests on files on other file systems than reiser4 did not show this behaviour. I tested on two different Systems, one Pentium M and one Athlon, same result. I wish I knew what I am doing wrong. I'd bet you guys all have reiser4 up and running with 2.6.14 and no problems at all. Or what?=20 best regards, Fionn --=20 Taking away civil rights to protect a free democracy is like taking off the tires of a car to protect it from flats.=20 --=-4ssAS4quDM6tn88XCBjj Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQBDZ469jkvYSI4bFywRAmfyAJ0Unm0lnZ1/AiUKa5M6MpN7yeFH1QCfRJjj BM2rAuaXsI9Ycz4jrcQ5OPY= =/dTd -----END PGP SIGNATURE----- --=-4ssAS4quDM6tn88XCBjj--
