Is this still a problem with 1.3.1.1? Just bumped it in cvs. Due over 2 months now, please reopen if it is still an issue |
I use gentoo-sources-2.6.14-r4, with fuse and nfs4 in the kernel (not a module), /home mounted with nfs4, and .mozilla in an encfs file system not running at root. When i try to run firefox, encfs and this nfs4 partition crash, i have to reboot. Reproducible: Always Steps to Reproduce: 1. use fuse and nfs4 compiled in kernel 2. move .mozilla to an encfs fs on a nfs4 mounted partition 3. launch firefox Actual Results: box crash, have to reboot it. Still usable if not using crashed nfs4 partition Expected Results: run without crash message log when crash : Dec 15 02:37:28 bounty Kernel BUG at fs/nfs/nfs4xdr.c:841 Dec 15 02:37:28 bounty invalid
