Just for reference here's my 2+ years old Asus A4K, kernel is form
Debian Etch:
deen:/tmp# uname -a
Linux deen 2.6.18-4-amd64 #1 SMP Mon Mar 26 11:36:53 CEST 2007 x86_64 x86_64
deen:/tmp# lsmod | (read a; while read a b c; do S=$((b+${S=0})); done; echo $S)
1583684
deen:/tmp# lsmod | grep xfs
xfs 485192 3
deen:/tmp# dmesg | grep kernel\ code
Memory: 506676k/523520k available (1930k kernel code, 16456k reserved, 868k data, 176k init)
Apart from diff in hardware and implied designing/coding skills, decision
was made
* after one "wrong" response plus illness from Con,
* brave core-duo by Ingo and Tomas, who made some bunch of students to test
scheduler and reported success to Linus.
I don't know why, after all that variety of things (mostly drivers, but
recent *fd also) there's such big resistance to anything that's useful
and used by ordinary people. A star sickness, pride? If yes, that's just
ridiculous, but who cares.
