Yes, it's the same hardware that was working on FC5.

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,
