It seems that the command

readcd -c2scan

fails on both of my drives for all media types - retail CDs, copies of
CDs on CR-R and CD-RW. It always hangs. It hangs at different places
if I rerun it.

I've never experienced any problems like this with the drives. It
seems very strange that suddenly both drives in this system, one drive
in my wife's system, and my car's CD player would all go bad. Very
unlikely.

Any comments about the rt-sources real-time kernel? I've used it for
years and never had problems, but for clarity I'm not currently using
gentoo-sources. Other than that most software on this machine is
stable/non-testing. The machine is actually AMD64 running 64-bit
Gentoo if that matters. Never has before and my wife's machine is
32-bit.

Strange days...
