Date: Wed, 23 Jul 2008 00:45:30 +0300 From: denys@...p.net.lb To: Jarek Poplawski <jarkao2@...il.com> Cc: denys@...p.net.lb, netdev@...r.kernel.org Subject: Re: NMI lockup, 2.6.26 release Well, i cannot see similar or not, only guess. Machine is crashing after few days, even without neconsole. Sometimes rebooting, sometimes not. So sometimes i am getting call at middle of night and running to power switch to reboot PC. I cannot check screen, it is in unreachable for me area. This bug probably is since 2.6.23 even... I will engage kexec with panic kernel just to be more safe, since it is not always rebooting over panic sysctl. As i see in sources path to panic kexec kernel is much shorter...
