Red Hat Bugzilla – Bug 19922
lost timer interrupts (*severe*)
Last modified: 2007-04-18 12:29:31 EDT
massive loss of timer interrupts and hence system time is dramatically
behind rtc clock (and dramatically behind our place in the space-time
continuum as well).
losses of >20% wall time not unusual.
symptoms manifest when:
* ripping cds (setuid root, real-time scheduler)
* burning cds (setuid root, real-time scheduler)
* playing mp3s with xmms (*not root*)
hardware config (see wozzle.geeksrus.net on rhn):
asus pc3j133 (?i'm at work, not home?)
atapi cdrom as hdd
tdk atapi cd-rw as scd0
creative audio pci (es1371)
diamond supraexpress 56k usb modem
logitech usb mouse
voodoo 3000 agp video
smc pci 10/100 ethernet
There is a known problem with via chipsets and losing time. It seems to
sometimes reset itself to
a frequency of 18Hz (the Windows default) while Linux programmed it to 100Hz.
It should be worked around as of the Linux 2.2.19-pre1 kernel.
