Hi,
I'm using vanilla 2.6.32.7 domU kernel with Xen 3.2 and get very often a unresponsible system after approximately one or two days with messages such as
[43616.674502] CE: xen increasing min_delta_ns to 16086592372704132408 nsec [43616.674502] CE: xen increasing min_delta_ns to 5683144485346646996 nsec [43616.674502] CE: xen increasing min_delta_ns to 17748088764874746302 nsec [43616.674502] CE: xen increasing min_delta_ns to 17398761110457343644 nsec [43616.674502] CE: xen increasing min_delta_ns to 7651397591976463850 nsec [43616.674502] CE: xen increasing min_delta_ns to 2253724351109919966 nsec [43616.674502] CE: xen increasing min_delta_ns to 3380586526664879948 nsec [43616.674502] CE: xen increasing min_delta_ns to 5070879789997319922 nsec [43616.674502] CE: xen increasing min_delta_ns to 7606319684995979882 nsec [43616.674502] CE: xen increasing min_delta_ns to 11409479527493969822 nsec [43616.674502] CE: xen increasing min_delta_ns to 17114219291240954732 nsec
on the console. I fail to login via ssh and even to cleanly shutdown this system via xm <id> shutdown. sysrq requests still work.
I searched the net but found only messages with 15000 nsec. My values are a little bit larger :-)) Found references to the kernel parameter notsc and tried it but the problem remains.
The problem started once I upgraded the kernel from 2.6.26 to 2.6.32.7. I changed from 32bit to 64bit but apart from this I did only a make oldconfig. That's why I think it's not my config which causes trouble.
Any ideas? Is it a known problem?
