>Description:
kernel panics since freebsd kernel 4.2, on average of every 20 days i get
/kernel: panic: ffs_clusteralloc: map mismatch
/kernel: panic: ufsdirhash_lookup: bad offset in hash array
or
/kernel: panic: ufsdirhash_lookup: bad offset in hash array
/kernel: syncing disks... 19 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
/kernel: giving up on 1 buffers
and then automatic reboot
often happens during syste mload. but cannot reproduce the panic myself.
>How-To-Repeat:
don't know, it just happens
>Fix:
don't know how to fix. will try turning off UFS_DIRHASH and
update kernel. (have tried updating kernel since 4.2 but
doesn't work)
