Just clean installed F15 i386 (AKA RC3) in this machine, with the same optical
drive, running kernel-2.6.38.6-26.rc1.fc15.i686.PAE. Reading the same 4 CDs, CD
1 has a read failure just 2048 bytes from the end. CDs 2, 3, and 4 can be read
all the way to the end. The parts that can be read are correct (using wget -c
on the first image, and then verifying the sha1sum of all images). I don't know
if this is progress or not. Are there any kernel changes that might have
reduced the severity of this bug?
