That stated, I built world using http://people.freebsd.org/~mm/patches/zfs/v28/releng-8.2-zfsv28-20110301-nopython.patch.xz and http://people.freebsd.org/~mm/patches/zfs/v28/stable-8-zfsv28-20110301-nopython.patch.xz. I am running a single-disk ZFS root filesystem (version 15). My make.conf contains CPUTYPE?=athlon64, machine has 4GB RAM. After extremely extensive testing, the RELENG_8 kernel is working well thus far (uptime 4:36), cvsup performed last night. RELENG_8_2 caused processes on the system to grind to an unrecoverable halt. As soon as I noticed my skype application taking 100% CPU time, my next attempt was to launch firefox. truss -f firefox revealed that the process hung after a stat call to a specific file: 67894: stat("/usr/local/etc/fonts/fonts.conf",{ mode=-rwxr-xr-x ,inode=240214,size=5223,blksize=5632 }) = 0 (0x0) As an experiment, I performed the following: ls /usr/local/etc/fonts/fonts.conf This command hung immediately and, like my other processes, was un-killable. Any attempts to stat the inode in question resulted in further cookie-eating. In order to rectify the issue, the machine required reboot; of course, rebooting was impossible without pulling the plug. Please let me know if further information / test cases executed on the RELENG_8_2 patched kernel. Regards, Jeff
