I have an MSI Wind purring happily along using a custom-compiled
2.26.29-rc3-rt6 kernel. Main reason for not using vanilla rt Ubuntu 9.04
kernel is that we discovered having issues with hibernation. Everything
works out-of-box including webcam, wireless, standby, hibernate, compiz,
64x2 jack on internal soundcard at 48KHz (this actually breaks Pd apparently
as it cannot handle such small buffers and gets zombified :-) etc. I guess
the reason I am posting this is if anyone would like to try DISIS version I
would greatly appreciate any feedback. You can get it from
<http://ico.bukvic.net/Linux/Kernels/>. If interested, I can also upload
latest version with debugger disabled which brings the download down from
277MB to roughly 25MB...
FWIW, as an added bonus, MSI Wind laptops have a manufacturer built-in BIOS
feature allowing CPU overclocking from 1.6GHz up to 2GHz by simply pressing
fn+f10.

Cool. I have an Eee 701 on which I installed "Ubuntu Eee" (an
unofficial buntu), and then I recompiled the "array kernel" (kernel
tweaked for the eee, "2.6.27-8.17eeepc1" I think,
<http://array.org/ubuntu/>) with the realtime patches added. I didn't
overclock - I have had no problems with SD cards.
That aside, I had a very similar experience to you: solid low-latency
audio I/O as long as I deactivate networking (I habitually just turn
off wifi from the eee-control applet). I do realtime
analysis/processing/synthesis using supercollider.
I also have an Eee using the stock Xandros which doesn't have an rt
kernel but (as long as you sudo) is surprisingly solid for realtime
audio.

Following on from Ken Restivo's amazing work
getting RT linux
working on the eeepc, I decided to have a go. I am using a 701,
which I have slightly overclocked using the eee.ko module
(required on my eee to boost voltage to get SD cards working
reliably YMMV).

I patched the latest 2.6.29.2 kernel with the rt11 patch, and
just built it...
Running Jack with qjackctl, I can set periods to 128, full
duplex, 44100 and get no xruns. I have to set prio to 89, and
force 16 bit. Importantly, I also have to kill NetworkManager and
NetworkManagerD or I get xruns. With all this, it seems really
solid. I am running ardour with no problems.. 6 individually
recorded tracks writing to the SD card seems to work fine.
