Subject: attempting task abort with block: remove artifical max_hw_sectors cap
Date: Tue, 06 Jan 2015 12:16:35 +0100 [thread overview]
Message-ID: <54ABC413.6090000@profihost.ag> (raw)
Dear list,
while testing 595b8ecd47e4dde64f704bf78d8c9b97e070ac67 ([PATCH] block:
remove artifical max_hw_sectors cap), i came around a problem with some
crucial m500 ssds direct attached.
With the patch applied, i see the following max_sectors_kb value:
# cat /sys/block/sdi/queue/max_sectors_kb
16383
But this results in the following error messages (at random time - most
probably at high load):
