Subject: 4.5-rc iser issues
Date: Sat, 13 Feb 2016 23:41:19 -0800 [thread overview]
Message-ID: <20160214074119.GA24558@infradead.org> (raw)
iSER on 4.5-rc3 seems to fall over pretty quickly for me. The
test is a a single LUN, against a Linux iSER target, also running
4.5-rc. Both are usinx mlx4 hardware. These messages appear
immediately when running xfstests on xfs (but not during mkfs.xfs),
and after a few dozend tests with ext4, and ultimiately lock up the
system:

When hacking the initiator to use FRs instead of FMRs I get something
fairly similar:

Feb 13 22:49:18 redstar37 kernel: [ 277.587677] iser: iser_fast_reg_mr: failed to map sg (5/6)
The only other kernel version I had available quickly is 3.16 from Debian
Jessie, and that works fine.
