According to strace, it seems to do the same thing in an endless loop (about 13000 times per second while stracing it): ppoll([{fd=4, events=POLLIN}, {fd=27, events=POLLIN}, {fd=28, events=0}, {fd=33, events=POLLIN}, {fd=9, events=POLLIN}, {fd=22, events=POLLIN}, {fd=29, events=POLLIN}, {fd=32, events=POLLIN|POLLERR|POLLHUP}, {fd=32, events=0}, {fd=31, events=POLLIN}, {fd=30, events=POLLIN}, {fd=23, events=POLLIN}, {fd=26, events=POLLIN}, {fd=16, events=POLLIN}, {fd=19, events=POLLIN}, {fd=15, events=POLLIN|POLLERR|POLLHUP}, {fd=15, events=0}, {fd=14, events=POLLIN}, {fd=13, events=POLLIN}, {fd=6, events=POLLIN}], 20, NULL, NULL, 8) = 1 ([{fd=28, revents=POLLHUP}]) I attached gdb to it, result: (gdb) bt #0 0x00007fae575e4f57 in ppoll () from /lib64/libc.so.6 #1 0x00007fae59d03457 in pa_mainloop_poll () from /usr/lib64/libpulse.so.0 #2 0x00007fae59d04799 in pa_mainloop_iterate () from /usr/lib64/libpulse.so.0 #3 0x00007fae59d04850 in pa_mainloop_run () from /usr/lib64/libpulse.so.0 #4 0x000000000040a19a in main () Unfortunately I have no idea what caused pulseaudio to take all the CPU, therefore I can't offer a reproducer. I hope the infos in this bugreport can give you some insight. Some details about my system: - Dell Vostro 1710 laptop - openSUSE 11.2 64bit with all updates + nearly all test updates as of today - KDE 4 - running programs: several KDE apps (KMail, Gwenview, Konqueror etc.) + GIMP - I also used mplayer tonight (not sure if is related) - pulseaudio runs with normal (nearly no) cpu usage again after killing the process taking 100% cpu # hwinfo --sound 13: PCI 1b.0: 0403 Audio device [Created at pci.318] UDI: /org/freedesktop/Hal/devices/pci_8086_284b Unique ID: u1Nb.6k+7+p1inn5 SysFS ID: /devices/pci0000:00/0000:00:1b.0 SysFS BusID: 0000:00:1b.0 Hardware Class: sound Model: "Intel 82801H (ICH8 Family) HD Audio Controller" Vendor: pci 0x8086 "Intel Corporation" Device: pci 0x284b "82801H (ICH8 Family) HD Audio Controller" SubVendor: pci 0x1028 "Dell" SubDevice: pci 0x0275 Revision: 0x03 Driver: "HDA Intel" Driver Modules: "snd_hda_intel" Memory Range: 0xf8300000-0xf8303fff (rw,non-prefetchable) IRQ: 22 (31634 events) Module Alias: "pci:v00008086d0000284Bsv00001028sd00000275bc04sc03i00" Driver Info #0: Driver Status: snd_hda_intel is active Driver Activation Cmd: "modprobe snd_hda_intel" Config Status: cfg=no, avail=yes, need=no, active=unknown BTW: The symptoms match bug 558119, but I don't have any "via" driver loaded. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
