>Description:
(please disregard "class" field above)
Greetings,
I seem to have difficulties with the interaction between ahci(4), ada(4)
and the CAM subsystem on RELENG_8. Perhaps my HDD is quirky (Samsung
HD103SI rev. 1AG01118), perhaps ahci or ada. (dmesg below)
I seem to have two problems:
1. the problem is that once in a while queued ATA commands time out, and
let the computer freeze for like half a minute or two. It then recovers.
This only ever affects the Samsung drive, I've never seen it on the
Western Digital. Either drive doesn't report any suspicious data to
S.M.A.R.T. - no pending blocks, no past reallocations, no parameters
even close to Thresh, no self-test failures. Possibly the Samsung also
has firmware quirks, silent limits and so on, I know there were firmware
updates to avoid data loss for larger siblings in the same drive series,
but apparently not for the HD103SI.
2. Trying to reduce the number of tagged openings with camcontrol tags
ada1 -N 16 doesn't work because min == max;
trying to disable tagged negotiation through "camcontrol negotiate ada1
-T disable" does not have any visible effect.
This is my /boot/loader.conf:
ahci_load="YES"
atapicam_load="YES"
cuse4bsd_load="YES"
geom_journal_load="YES"
sem_load="YES"
snd_hda_load="YES"
vboxdrv_load="YES"
hw.ata.wc=0
kern.cam.ada.write_cache=0
kern.ipc.shmall=32768
kern.ipc.shmmax=67108864
kern.maxfiles="25000"
vfs.root.mountfrom="ufs:/dev/ada0s4a"
This is dmesg with sensitive and useless information omitted. At the
end, it shows two episodes with freezes, of a handful of timeouts each
time.
