Hi,

2.4 IDE was (re)written on top of the old ide code by Andre Hendrik.  Seems
that Andre, who it seems does really understand IDE and its quirks, can be
a pain to work with...  In early 2.5.x Linus started taking patches from
Marcin (or Martin) Dalecki.  Since then, with over a 115 patches, Marcin
has proceeded to rewrite the IDE code.  This has tended to make IDE a bit
unstable in 2.5.   About 2.5.26ish Jens Axobe got tired of the 2.5 ide
problems and ported 2.4 ide to 2.5.  This change was picked up in the Dave
Jones series of kernels - it allows other pieces of the kernel to be tested
while Marcin works towards a cleaner IDE.

IDE 2.5 is stable for some but not for others (like me) depending on it is
iffy - have backups.  If you do not want to test 2.5 IDE use -dj (Dave is a
bit behind Linus now due to other work and a much needed vacation)
