Daniel, I applied the method indicated at the link you sent. Copied / pasted / executed:
touch ~/.pulse_a11y_nostart echo autospawn = no|tee -a ~/.pulse/client.conf killall pulseaudio and rebooted the machine. That didn't prevent pulseaudio from starting, though, as my log still contains: Nov 22 16:44:53 Philinux kernel: [ 28.182386] __ratelimit: 3 callbacks suppressed (...) Nov 22 16:45:05 Philinux pulseaudio[1697]: ratelimit.c: 1 events suppressed Nov 22 16:45:58 Philinux kernel: [ 93.244043] Clocksource tsc unstable (delta = -216722338 ns) What gives?... > PulseAudio is entirely userspace. Are you referring to > the ALSA kernel modules (sound drivers)? Well, the reason I'm asking is that I repeatedly see various processes segfaulting within a dozen microseconds after a __ratelimit: X callbacks suppressed messages, I inferred that some pulseaudio kernel module was involved: How could the pulseaudio usermode process interfere with a whole set of other user processes otherwise? Or send the whole OS to a freeze? Example follows: Nov 21 14:09:42 Philinux pulseaudio[1842]: ratelimit.c: 2 events suppressed Nov 21 14:10:05 Philinux kernel: [ 94.732041] Clocksource tsc unstable (delta = -223109891 ns) Nov 21 14:10:38 Philinux kernel: [ 127.890435] __ratelimit: 3 callbacks suppressed Nov 21 14:10:38 Philinux kernel: [ 127.890447] apt-check[2885] general protection ip:805b17c sp:bf88202c error:0 in python2.6[8048000+1d3000] Nov 21 14:11:35 Philinux kernel: [ 184.778508] update-manager[2935] general protection ip:809494a sp:bfae3134 error:0 in python2.6[8048000+1d3000] Finally, my apologies for answering to you as "Peter" in my previous message.
