Since upgrading to 4.2 (from 3.somethingorother), my cdrom has
been misbehaving. Reproducibly, by doing an ls -R on the 4.2
RELEASE cdrom, I get
acd0: READ_BIG - ILLEGAL REQUEST asc=64 ascq=00 error=00
periodically. It happens at more or less predictable spots but I
don't think it's a bad CD; I can use the CD elsewhere. Also, it's
not jumpers -- I fiddled with those and the problem didn't go
away. I should also mention that the ls -R more or less works
except that some directories don't appear. However, cd'ing to
those directories and doing an ls works.
The system has been upgraded to 4.2-STABLE as of yesterday
afternoon and the problems are still there. Here's the dmesg
output:
