It could some overheating problem but i think if it is, this is the first t= ime=20 it occurs :), and i don't have any array, SAMSUNG HM120JC IDE disk works on= =20 SONY VAIO FS-215B. I just boot with plain CFSv7 and boot time seems normal;=20 Apr 29 15:02:54 (up 10.72) /sbin/mudur.py sysinit Apr 29 15:03:02 (up 17.26) /sbin/mudur.py boot Apr 29 15:03:06 (up 21.34) /sbin/mudur.py default I'll report if i can find any reproducable problem, so far CFSv7 works as=20 expected :) Cheers =2D-=20 S.=C3=87a=C4=9Flar Onur http://cekirdek.pardus.org.tr/~caglar/ Linux is like living in a teepee.
