Subject: Sky2 2.6.36-09934-g2aab243 DMAR error with tcp timestamp enabled
Date: Sat, 06 Nov 2010 12:57:53 -0400 [thread overview]
Message-ID: <4CD58911.3050201@majjas.com> (raw)
In-Reply-To: <4B69AD5C.5030601@majjas.com>
Basically, if I enable tcp timestamps (now disabled) I get a sky2 hang.
As with the earlier issue the effects are not seen until after a couple
days of uptime and seem exacerbated by load.
I can't 100% confirm that the problem is not occurring without tcp
timestamps, but will leave the system up for a while to try to confirm.
This didn't occur previously without tcp timestamps enabled, but I also
pulled git changes between the two events.
I'm now also on 2.6.37-rc1.... I did a quick scan and didn't see any
obvious commits between 2.6.36-09934 and -rc1 that would have affected this.
From the log:
