IMO it would probably easier on all involved if the comment noted what
you state in the patch description.

The Dell DRAC4 has some interesting features including effectively hot
unplugging/replugging the virtual CD interface when the DRAC is reset.
This often causes drivers/ide/siimage to panic but is ok with the rather
smarter code in libata.
Just note this fact in the driver docs.

Alan, please send me the actual OOPS if possible.

You have a wide choice of oopses, watchdogs and hangs available.
Basically the device vanishes and in some cases we end up stuck in a
tight loop with the old IDE layer trying to get to talk to it and then
die in an NMI watchdog.
If you are interested in the actual dumps let me know. I'll need to clear
it with originator of the reports.
