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
