@m.morana - to my knowledge modern kernel's still don't have a namespace
aware ISCSI netlink implementation. In an OpenStack context, I recall
seeing something about changing nova's volume attach code to use qemu's
native iSCSI support which may be a workaround for iscsiadm and native
block
3.13.0-43.72 does not exhibit this bug with testing, so I think we can
close this issue.

NUMA stability), so this is an improvement over 3.13.11.11.

Title:
Trusty isci module doesn't handle timeouts properly
Status in “linux” package in
After a night of stress testing with the 3.18-rc5 packages I have not
been able to reproduce an unhandled SAS/SCSI event (the new kernel did
intensely dislike NTP and apparmour, but that's an other issue
altogether).
There were only two 'sas_scsi_recover_host' events early in the boot
process:
I've installed the 3.18.0-031800rc5.201411162035 kernel packages and am
running load on the box now to see if I can get it to hiccough. Will

I have seen mentions of isci and libsas getting timeout fixes, and I
know that 3.18 is using newer libsas and isci code than we have in 3.13.

I'm also curious about an update on this issue. I'm running 14.04.1,
Kernel 3.13.0-39-generic and LXC 1.0.6-0ubuntu0.1. 'strace' output of
open-scsi looks basically the same as above.
As I understand it, this is related to iSCSI's Netlink implementation
not being namespace aware? I would love
