Then I will be doing some headscratching over a copy of the kernel.
Oh--  what *exact* kernel are you using?  non-x86 trees don't always
sync often with the 'official' mainline and I want to be sure I'm
reading the correct thing.  I was a longtime PPC user until about two
years ago, and I'm used to there being several substantially different
PPC kernel trees [just making sure].

OTOH, if the kernel isn't even servicing the device as a block device
until the drive returns a ready status and O_NONBLOCK thwarts waiting
for that.... sigh.  Nothing like a passthrough interface that still
isn't a passthrough interface after fifteen years of dicking around.

I'm not willing to cripple cdparanoia on more-than-one-cdrom systems
because of an edge case due to yet another ill-considered block layer
'feature'.  For one thing *I* need to be able to scan devices without
blocking on my own multiple drive systems.  If there's a workaround to
get both, I will find it.

But it's too early to say for sure.  I'll check again.

(May I ask-- why the hard starting/stopping of the interface?  Power saving?]
