hdc (cdrom) irq timeout after awaking from sleep on powerbook

Hi...

When I insert + mount a cdrom and then put this powerbook to sleep mode, I keep getting these messages in the kernel log when the machine wakes up. However I can still access the cdrom on its mount point as if everything was ok... but is it ?

This is kernel 2.6.7-rc2 on powerbook g4 1Ghz.

Please comment,

VFS: busy inodes on changed media.
hdc: irq timeout: status=0xc0 { Busy }
hdc: irq timeout: error=0xc0LastFailedSense 0x0c
hdc: DMA disabled
hdc: ATAPI reset complete
VFS: busy inodes on changed media.

Well... at least it lost the DMA which isn't good. But our driver tends to be a bit nasty for that. We may probably want a smarter wakeup sequence for ide-cd that the current one that does nothing (just use the default IDE one which is to wait for BUSY to be gone). I suspect some ATAPIs would love getting a new WIN_PIDENTIFY at least, and I've seen some take time before actually _raising_ BUSY ... I'll look into it.
