Hi All,
I keep getting the following messages (mostly under high load). Under sufficiently high load (make -j 8 world and a few more I/O intensive processes) the machine becomes unusable with these messages happening every few seconds.
(da1:ahc0:0:1:0): SCB 0x5 - timed out while idle, LASTPHASE == 0x1, SEQADDR == 0
x9
(da1:ahc0:0:1:0): Queuing a BDR SCB
(da1:ahc0:0:1:0): Bus Device Reset Message Sent
(da1:ahc0:0:1:0): no longer in timeout, status = 353
Unexpected busfree. LASTPHASE == 0xa0
SEQADDR == 0x14f
I know someone asked the same question very recently and the suggestion was to check the drives firmware. I haven't been able to find any info on how to update the firmware on my drives (Conner CFP2107E) and would really doubt there is any upgrades out there (though if anyone knows any different please let me know).
Anyways this is a very recent kernel (< 1 week old), the dmesg output is listed below. This seems to happen more often when I have the drives mounted async and happens on both da1 which is a vinum subdisk and da0 which is my main drive (I haven't noticed the problem on da2, though it may happen there too). If you have any suggestions on how to get rid of these errors I would really appreciate it.
