Hello, I have an "easily" (at least to me) reproduceable freeze with both 6-STABLE and 7-CURRENT on an amd64 SMP machine. What I do is simply copy a lot of directories, files and symlinks with different uids from another machine to this one, using rsync. With quotas enabled it freezes constantly, without quotas it doesn't. I have MP_WATCHDOG enabled (the kernel config is the default GENERIC+SMP with debuggers and MP_WATCHDOG only) so after the freeze it drops me into the debugger in which I can see the following: FreeBSD/amd64 (helen) (ttyv0) login: Watchdog timer: 3 Watchdog timer: 2 Watchdog timer: 1 Watchdog timer: 0 Watchdog firing! NMI ... going to debugger [thread pid 157 tid 100143 ] Stopped at vinactive+0x83: jz 0x365245a9 db> bt Tracing pid 157 tid 100143 td 0xffffff007b9c14c0 vinactive() at vinactive+0x83 vput() at vput+0x1cf qsync() at qsync+0x260 ffs_sync() at ffs_sync+0x159 sync_fsync() at sync_fsync+0x191 VOP_FSYNC_APV() at VOP_FSYNC_APV+0x3d sched_sync() at sched_sync+0x428 fork_exit() at fork_exit+0x86 fork_trampoline() at fork_trampoline+0xe --- trap 0, rip = 0, rsp = 0xffffffffb2029d00, rbp = 0 --- db> ps 157 ffffff007b9489c0 0 0 0 0000204 [CPU 0] syncer Any ideas?
