As for Sound: I rarely use the SD-reader (sdhci:slot0 - BTW. unloading
the module saves power!) so I connect a USB UA-25 to either IRQ22 or
IRQ23. even if it's the only device on that bus I get rare xruns on 64
frames/period. but a robust setup with `jackd -R -P 70 -d alsa -d hw:1
-p 256 -r 48000` makes this Thinkpad a great machine for
stereo/binaural audio work and fun! - (recap: the Dell D820 seems
somewhat better suited for pro-audio, and a Vaio sz3 is similarly good,
but sony&linux requires a little more some devotion..)
I'm curious: where did you get information that the Dell D820 is better
suited? I'm wondering if there is some info available about the IRQ
mapping in the D820 which can help me make a decision whether to get the
Dell D820 or a Lenovo T60p.
This is for my D820 and stock ubuntu feisty kernel.
