The following reply was made to PR kern/179932; it has been noted by GNATS. From: Markus Gebert <markus.gebert@hostpoint.ch> To: bug-followup@FreeBSD.org, =?iso-8859-1?Q?Philipp_M=E4chler?= <philipp.maechler@hostpoint.ch>, "sean_bruno@yahoo.com" <sean_bruno@yahoo.com> Cc: Subject: Re: kern/179932: [ciss] ciss i/o stall problem with HP Bl Gen8 (and HP Bl Gen7 + Storage Blade) Date: Fri, 28 Jun 2013 15:23:25 +0200 I already replied to Sean last friday but the copy has not made its way = into the PR system, probably due to the size of the alltrace attachment. = So here's a dropbox link: = https://dl.dropboxusercontent.com/u/10669369/alltrace%20G8%20PERF%209.1cis= s.txt And the email I sent: ---- Hi again One of the G8 blades we had booted back into PERF mode yesterday stalled = last night. This one was _not_ patched with the ciss changes from head, = so it was the plain 9.1 driver running in default PERF mode. This means = that as soon as we restore the original default configuration, the = stalls come back quite quickly. Of course we still don't know wether it = is the patch, SIMPLE mode or the combination of both that seems to help = the other systems. Hopefully we'll know that soon. Anyway, we got an alltrace from the server that stalled. Unfortunately = no ciss debug outpout since it was not patched. Markus ----
