https://bugzilla.novell.com/show_bug.cgi?id=350980 Summary: The system stops doing things till I press a key or move the mouse: every things halts. Product: openSUSE 10.3 Version: Final Platform: i686 OS/Version: openSUSE 10.3 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: robin.listas@telefonica.net QAContact: qa@suse.de Found By: --- This is very weird. Sometimes, the system simply stops "working". Doesn't crash, simply all tasks seems stopped. Nothing refreshes in the display. The clock stops. A script running a loop in a console: #!/bin/bash while true ; do # date +"%T" | tee -a /home/cer/marca.log date +"%T" >> /home/cer/marca.log sleep 1 done stops as well. Then, as soon as I move the mouse or touch a key (shift, for instance) everything continues and the clock jumps some seconds or minutes to the correct time. I have tried several things, as discussed in the "opensuse" mail list (<http://lists.opensuse.org/opensuse/2007-12/msg01780.html>). No effect. - check the desktop for powersave features - nothing, and there is nothing configurable that would kick in in seconds of no user activity. - pass cpufreq=no as a boot argument --> no good. - Recompile the kernel with "NO_HZ" --> even worse (this is the current state). I will recompile again to undo. And more things I forgot, but you can read the whole story in the mail list or the link above. Sometimes, very random, the system stops completely and does not respond to keyboard, but it awakes when I boot another PC, which I think tries to connect or ask for a service (ntp or dns). My current hack is to leave my router continuously pinging me. My guess is that the pings cause the network card to interrupt the kernel, so it keeps awake. Keyboard or mouse also provokes interrupts. I'm not sure about usb activity. This might be related to other bugs reported by me, I don't know (spamd timeout?) I have been "playing" with the clock (Bug 344356 and a new one not reported yet). The thing is that the kernel defaults to using "acpi_pm" clock and this one misses whole minutes. I have to force use "tsc" (which kernel disabled at boot). jiffies crashes. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
