After some dialog with Terry Lambert on -hackers, I've been advised to
post this here.
I have a 4.7-RELEASE-p10 box that is suffering regular kernel panics.
The machine is a Dell 2650 running primarily as a file/print server to
a number of computer labs of about 400 machines (although it also
functions as a rembo image server and squid proxy). It mainly stores
applications, which are run off a samba share and user home directories
(again, accessed via samba). It has a largish filesystem (~200G) on a
Powervault 220 attached via a PERC3/DC controller (amr) that most of
the data is stored on. The OS is on a pair of internal 18G drives
attached to the internal PERC3/Di controller (aac). It is attached to
the network with a Netgear GA620 fibre NIC (ti).
The panic is being triggered by the "find" run in
/etc/periodic/daily/100.clean-disks. Disabling this script has, for
the moment, circumvented the problem - although from what I can gather
it is a kernel bug.
The machine is scheduled to be updated to 4.8 in two weeks. If anyone
knows if this issue has been resolved already, please let me know. If
it hasn't, or the status is unknown, I'd be quite happy to re-enable
the daily script triggering the problem once the system has been
upgraded and provide the necessary crash dumps, etc to help solve it.
Terry tells me it has been fixed in -current.
Here is the relevant system info. If I've forgotten anything, or there
is anything more anyone needs to help fix the problem, please let me
know.
