Subject: [linux-audio-user] Can low-latency patch cause CPU freeze?

I've installed a 2.4 kernel with low latency patches by downloading the
Planet CCRMA rpms.
Since then, I've noticed that after a period of time after bootup, I get
a hard freeze in X - Neither Ctrl-alt-BS nor Ctrl-alt-del does anything,
and the mouse cursor dissapeears. I don't have an other terminal handy
to check if I can log in through a serial port. But I'm pretty sure it's
hardware related because when this happens, the computer does not boot
up for a period of time, giving the sequence of long beeps like a RAM
error.
I suspect that given the pattern over time, I have an overheating
problem somewhere, and was wondering if anyone can think of any reason
that the low-latency patches could contribute to this. I'm not
suspecting the patches right way, because this could easily be
coincidence, but I'd thought I'd ask just in case for some strange
reason that patches could make the CPU run hotter. Actually, what comes
to my mind is that possibly the patches cause the cpu to enter an idle
loop instead of halting when idle, and this is enough to overwhelm my
CPU fan.
Yeah, I know, this is probably a half, uh, "baked" haha idea, but I just
wanted to throw this out to the list in case, indeed this could make a
difference. Again, it could easily be coincidental, but before I go
swapping hardware, I thought I'd ask just in case. In the mean time, I
will experiment by disabling the patch (echo "0" > /proc/lowlatency) to
see if it make a difference.
