Description of problem:
When starting up tvtime after updating to kernel-2.6.7-1.494.2.2 it
crashes. With kernel-smp-2.6.6-1.435.2.3 it worked just fine.

Snippet from syslog...

Version-Release number of selected component (if applicable):
kernel-smp-2.6.7-1.494.2.2

How reproducible:
Always

Steps to Reproduce:
1. start tvtime
2. watch it die with segmentation fault
3. take a look in syslog

Comment 1 David Juran 2004-08-07 22:46:20 UTC 
My mistake, this happens with the old kernel as well. Suddenly the
picture freezes and those masages about bttv timing out come up. Am I
crazy to think this was triggered by touching my USB mouse?
Comment 2 David Juran 2004-08-08 23:28:19 UTC 
Just noticed this in the syslog.

And from /proc/interrupts:

 19:      47306      52694   IO-APIC-level  EMU10K1, bttv0

Would this shed some light on the problem? Will try with acpi=off and
see if it helps...
Comment 3 David Juran 2004-08-10 21:54:11 UTC 
No, that was a false track... disabled ACPI and the messages about
screaming IRQ went away, but tvtime still fails and I'm still getting
those messages about bttv timing out and resetting.
Comment 4 David Juran 2004-08-31 20:19:05 UTC 
Just noticed that this seems to work with the uniprocessor
kernel-2.6.8-1.521 but not with the SMP version on my dual CPU machine.
Comment 5 David Juran 2004-09-15 17:41:43 UTC 
Adding the boot option noapic, as suggested by Erik Slagter, solves
(or at least works around) the problem.
Comment 6 Dave Jones 2005-04-16 04:08:01 UTC 
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat.  The Fedora legacy project will be producing further kernel
updates for security problems only.

If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.

Thank you.
