Subject: Possible regression with 3.13
Date: Mon, 18 Nov 2013 11:06:39 -0500	[thread overview]
Message-ID: <528A3B0F.7090502@oracle.com> (raw)

We appear to have a regression in 32-bit 3.13 Linux dom0 --- sometimes 
(often) dom0 gets stuck somewhere in RCU while running an HVM guest 
(with "INFO: rcu_sched self-detected stall on CPU..." message being the 
first indication of things not going well).

I believe this was brought in by 39cf275 merge. I am trying to bisect 
this merge but having a bit of tool trouble. While I am doing this, if 
anyone noticed any issues with 32-bit dom0 recently, please let me know.

I see this most often with 4.1 but I think unstable is also affected.
