Bug#412194: linux-image-2.6.18-3-k7: total system freeze after max. 10 minutes uptime



I can live single processor for a while. So yes reduction of severity is okay for me. But, I'm thinking that there are a number of k7-smp servers that are the truck horses of various clusters (esp. universities and small research groups) who mayn't tolerate the loss of utility.

Hello Steve,


uptime with "nosmp" so far: 57 min. Everything runs fine and smoothly. Of course overall system load is about 5 percent (average) to 20 percent (peak) higher than usual - man, i do love and miss smp.. :D

Just kidding, i can easily live happily either with "nosmp" or particularly with 2.6.17 for now. Maybe other affected users might agree to lower the initial severity to "important"?


But guess who appears on stage now again (dmesg log):

#Time: pit clocksource has been installed.
#...
#Real Time Clock Driver v1.12ac
#Generic RTC Driver v1.07

RTC is back for good!

This makes me so curios about the mysticals of linux time again:

http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=734efb467b31e56c2f9430590a9aa867ecf3eea1

After reading, re-reading and hopefully understanding i will try to find a solution, why 2.6.18-k7 decides to use "Programmable Interval Timer" of 1981(!) instead of our even younger and trusted friend "rtc" or even the fancy "acpi_pm" ..

Once i find helpful information or even a solution, i will post it here.


Thank you very much again!

Sure, it could be, but I don't know anything about the architecture of the
kernel's clocksource stuff.

Good luck,
