Subject: add delay around sl82c105_reset_engine calls
From: Olaf Hering <olaf@xxxxxxxxx>
The hald media changed polling does really confuse things. Noone knows why
the delays are needed, but they give us access to the CD.
An udelay(50) will give reliable access to the drive, but there is still one
(or more) EH reset. The drive works without EH resets with udelay(100).
