Exact same hardware as before? It does look like a kernel problem in the
mainline kernel.
Yes, it's the same hardware that was working on FC5.

I used one briefly to test it in my laptop. I was running 64x2 with no
problems, but the test was not very long.
The only thing that jumps at me from the data in the email are the
latencies of the pci bus cards. The pci cards that have them are set to
128 and the hdsp is set to 255. Is that because you tried to optimize
them?
I normally see latencies on the order of 64... If you lower them, does
it make any difference?

Those are the default pci latency timer settings. As you suggested, I
lowered the latencies on several devices:
00:01.0 PCI bridge: Intel Corporation 82855PM Processor to AGP
Controller (rev 21)
Latency: 16 (was 128)
01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility
Radeon 9600 M10]
Latency: 20 (was 128)
02:03.0 CardBus bridge: ENE Technology Inc CB1410 Cardbus Controller
(rev 01)
Latency: 32 (was 168)
03:00.0 Multimedia audio controller: Xilinx Corporation RME Hammerfall
DSP (rev 32)
Latency: 64 (was 255)
I set everything else to latency = 0, including ethernet, wireless, and
firewire (which I don't currently use anyways). Unfortunately, this
doesn't seem to have any effect on the symptoms. Does setpci perhaps
require either a system reboot or a restart of alsa? (btw, is
/etc/rc.d/init.d/alsasound missing in F7? I saw a few threads on this
for FC6, but there didn't seem to be a resolution). In any event, are
these new values more reasonable for a laptop? I did find a few
informative links on this issue, and it sounds like many people swear by
tweaking those latency values
(http://www.sabi.co.uk/Notes/linuxSoundLatency.html, which also includes
links to other pci latency pages, if anyone is interested).
Anyways, I will try disabling devices one-by-one this weekend, and if
that doesn't help, I'll probably try building an older kernel.
Thanks for the help,
