I'm not Big deal, 99% of ide-scsi use is for cd burning. But yes, it should be fixed. I'm not disagreeing, I just don't think it's a high prio item. And apparently noone else thinks so either, if not it would have been fixed a long time ago (it's been broken for how long now?) > sure of the problems in the 2.5 case, in the 2.4 case the big one was > that both IDE and SCSI want to control reset/recovery and reissue of > commands.

Once it bugs someone enough, that someone will do it. Until then, it remains broken :) -- Jens Axboe -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
