Hi Alan, for 2.4.21-pre5-ac2 and -ac3 patch also. there's still problem on reset. when I do 'hdparm -w /dev/hda' once after another, all seems ok. but when I make a shell script and let 'hdparm -w' run in several times loop, system would always crashed at the second time and left oops messages: kernel BUG at ide.c:1700! ... so, if any bugs still locking there?
