So far, the most stable 2.2.0 kernel for me has been 2.2.0-pre8!
2.2.0-pre9 introduced a bug that is still outstanding for a very
limited, small, tiny, insignificant problem (ide-scsi). I can wait.
Meanwhile, I am helping make it better by running and testing newer
kernels and carefuly reporting bugs to the authors if and when they
happen but only after reading the linux-kernel mailing list to make
sure I am not cluttering their inboxes with duplicate reports.
Right now my lilo.conf has entries for the lastest Alan Cox patch
of 2.2.1, vanilla 2.2.1 from Linus, and 2.2.0-pre8 so I can compare
and contrast.
