hi all,
I got the fallowing soft lockup error "BUG: soft lockup - CPU#0 stuck for 16s! [Playback Thread:9266"] is that 16s is the value of /proc/sys/kernel/softlockup_thresh ??
Not really . In loose terms, 16s is the value of difference in time when this process was last touched by this cpu.
if yes, can I get rid of that message/panic by setting softlockup_thresh to some value greater that 30 ???
You can set it to 0 or something less than 0 to avoid these triggers. See the function softlockup_tick() to see how the calculations are made to trigger soft lockups. Roughly the calculation is :- if "current_time - threshold" > "last time touched timestamp" trigger soft lockup. HTH ___________________________________________
