What gcc versions were used when compiling the kernels? (Boot both
kernels, run "cat /proc/version" to find out.)
I just discovered that the driver doesn't work correctly on my laptop
if I use "gcc version 4.0.1 20050727 (Red Hat 4.0.1-5)" from Fedora
Core 4. "pktsetup 0 /dev/hdc ; cat /proc/driver/pktcdvd/pktcdvd0"
OOPSes. If I use gcc32 it does seem to work though.
