Look in my headers, and you'll see:
X-Operating-System: Linux 2.5.66
2.5.59 would compile (gcc 3.2), but hang at boot. 2.5.66 runs, and runs
nicely, if you do the following:
1. Install module-init-tools, modutils is relaced.
2. Check your make menuconfig carefully, tons of options have been
shifted around, mostly in the direction of greater sensibility.
Still, I failed to compile serial (8250) drivers, the console code,
blegh.
3. ALSA is different than OSS, but working, now:
# ln -s /proc/asound/dev /dev/snd
2.5 seems faster. Disk I/O definitely changed, the disk actually sounds
harsher now, as the scheduler seems to drive the disk faster. I have yet
to compile a new kernel on 2.5 again, to see how it compares.
For those of you wishing to see this for yourselves, here's my dmesg
output so you can see what I'm running this on:
