Synopsis: Kernel panic (possibly inteldrm related)
Category: kernel
System : OpenBSD 6.1Category: kernel
Details : OpenBSD 6.1-current (GENERIC.MP) #0: Sun Jul 23 11:17:14 BST 2017
***@phase.tratt.net:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
Since the inteldrm update on both my desktop (a Skylake machine) and
laptop (X1 Carbon 3rd gen) I have experienced random kernel panics.
I've now had a ddb trace from both machines (both panic with "malloc:
out of space in kmem_map"). The first ddb (from the desktop) is here
(from a kernel a few days old; limited information as my keyboard didn't
work at the ddb prompt):
https://imagebin.ca/v/3UPGaXO2uK54
The second (from the laptop with snapshot from yesterday and a kernel
built today) is here:
https://imagebin.ca/v/3UPI4KUtloXi
and then various output from ddb (tar file with several JPEGs inside):
https://www.dropbox.com/s/xuhzpmftvz9vshj/ddb_output.tar?dl=0
extsmaild (http://tratt.net/laurie/src/extsmail/) appears to be causing
the final panic, but given that it's just in a "wake every 60 seconds
and see if new files have appeared in a directory" loop, I'm not sure
why. I have also tried killing it, and still experienced at least 1 or 2
panics (albeit not ones that have ended up in ddb), so I suspect
extsmaild is a symptom but not the cause. Interestingly, if I "boot -c"
and "disable inteldrm" the panics go away on my desktop (I haven't yet
tried this on my laptop).
The dmesg below is from my laptop with a snapshot from yesterday and a kernel
built today.
Happens intermittently (generally within a hour of light-to-medium
usage).
Unknown.
