There are many other options that you can try: "noapic", "hpet=disable", "nohz=off", "nolapic".
I have tried these using the 2.6.35-25-generic kernel in Kubuntu 10.10. It really felt like "noapic" worked: * No audio susceptibility * No susceptibility to heavy rt-benchmarking But it didn't: * rt-benchmark running as root was not scheduled for 977 ms when the machine was idling. This is not supposed to happen, right? * Could these messages (from the bottom of dmesg) be indicative of this bug, or is it just me?: [ 133.022562] CE: hpet increased min_delta_ns to 7500 nsec [ 345.032576] CE: hpet increased min_delta_ns to 11250 nsec [ 3988.069868] CE: hpet increased min_delta_ns to 16875 nsec [ 4218.910129] CE: hpet increased min_delta_ns to 25312 nsec [ 7493.620160] CE: hpet increased min_delta_ns to 37968 nsec [14360.431022] CE: hpet increased min_delta_ns to 56952 nsec "hpet=disable" did not work: * frequent hangs shorter than 0.5s (none above 1s, but did not test very long, did not test idling) * susceptible to rt-benchmark and audio playback nohz=off: same as hpet=disable "nolapic" works, meaning that reproducing an idle hang is at least beyond my patience (sorry for not being more scientific). Nothing going on in dmesg either. -- 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.
