--- Comment #161 from Andreas Nordal
Can anyone describe exactly what the issue is and how I can reproduce it
This is about system-wide hangs (no task making progress), that: * resumes immediately on user input (from keyboard, mouse, laptop lid, plugging AC power) * easily lasts for hours on some kernels if your patience permits, to speculatively small (centisecs) on others. In one occasion, X had the effect of limiting my hangs to just up under 1 second. * occur under light load — an effective remedy is to open a terminal and issue `yes`. A 100% effective workaround is "processor.max_cstate=1". * occurs more frequently when playing audio, running rt-benchmark, and running wget. How to reproduce: 1. Watch glxgears (or something that updates the screen) while playing audio. 2. Observe that glxgears hangs whenever your audio player hangs, and that sound is repeated for the duration of this hang. 3. If you're lucky, you may test your patience by letting it hang, and when you feel for it, move your mouse 1mm, and observe that all tasks resume. If you're less lucky and only see/hear small hangs, you may still observe that keeping your mouse in motion prevents hanging. The role of rt-benchmark is to measure duration of hangs. My affected laptop has a broken screen, so I'm no longer able to test. -- 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.
