I am not completely convinced this bug is the "block: support larger
block pc requests" patches fault. If I revert the jiffies_to_msecs usage
then it works for me. On my system I have
CONFIG_HZ_250=y
CONFIG_HZ=250

With the attached patch, nero finds the cd drives and I can burn disks.
There is no errors from the ide layer like before.
