2.6.18-rc1 Freezes on CDROM Access

[Srihari Vijayaraghavan]

When I insert a CD in the CDROM or CD-RW drive, it
freezes solid. No serial console output (OOPS, BUGs or
panics) or sysrq response.

I narrowed it down to 2.6.17-git21-git22 (using the
daily git snapshots), which is rather a huge patch.
Any particular candidate?
