Red Hat Bugzilla – Bug 228027
high pitched noise
Last modified: 2008-05-06 21:09:15 EDT
Laptops with cheap capacitators makes a high pitched noise. The problem is explained and "resolved" in http://bugzilla.kernel.org/show_bug.cgi?id=7973#c3 So fixing it for real will require that: if laptop timer interrupt == 100Hz fi
eventually we'll be moving to a tickless kernel, which should solve the problem by not waking up at a fixed frequency at all.
I wonder just what that tickless kernel would sound like? Might be even more annoying than a steady noise in some cases...
it depends on the frequency at which userspace will cause wakeups. There's ongoing effort to reduce unnecessary wakeups. (See https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=wakeup for some horrors) If userspace isn't waking up frequently, then it should sound no worse than CONFIG_HZ=100
Moving to 'devel' as discussed on https://www.redhat.com/archives/fedora-devel-list/2007-March/msg00095.html.
