Well... I knew that it was, erm, brave to use it at some time (this box
isn't really important - if I kill its filesystems, I'll simply
re-install and recover my mirror scripts:) ,  but new, where 2.5.x
starts to be really useable, I'd suggest to face users with upcoming
problems:

CONFIG_IDE_TASKFILE_IO
	It is safe to say Y to this question, in most cases.

	(By the way, exactly which cases are ment?)


CONFIG_BLK_DEV_IDE_TCQ
	If you have such a drive, say Y here.


CONFIG_BLK_DEV_IDE_TCQ_DEFAULT
	Generally say Y here.


CONFIG_BLK_DEV_IDE_TCQ_DEPTH
	You probably just want the default of 32 here.

	(Default queue depth is 8, not 32...)


Right now, I'm building 2.5.73-bk3 + your 2nd patch. Let's face it:)

MfG, JBG
