[-- Attachment #1 --] Hi, A recent change (r193174, r193186) in vfs_cache has been causing __getcwd to panic the system. The panic appears to trigger when I try install lang/ezm3 (with other things also happening). -- hand copied --- System call _getcwd returning with the following locks held: shared rw Name Cache (Name Cache) r = 0 (0xc0eced7c) locked @ /usr/src/sys/kern/vfs_cache.c:1104 panic: witness_warn --- above reproducible --- cpuid = 2 KDB: enter: panic [thread pid 23322 tid 100190 ] Stopped at kdb_enter+0x3a: movl $0, kdb_why db> cont Uptime 20m35s Physical memory: 3055 MB Dumping 271 MB: 256 240 224panic: bufwrite: buffer is not busy??? cpuid = 0 KDB: enter: panic [thread pid 25 tid 100055 ] Stopped at kdb_enter+0x3a: movl $0, kdb_why db> cont Uptime: 20m36s Automatic reboot in 15 seconds - press a key on the console to abort Rebooting... cpu_reset: Stopping other CPUs --- systems hangs here, does nothing else --- --- hard reset --- I reverst the change (and r193175) and the panic 'disappeared'. Willing to test patches.
