I would suggest trying the following things:

1) Add both drives ("_NEC DVD_RW ND-3520" and "TSSTcorpDVD-ROM
TS-H352A") to ata_device_blacklist in drivers/ata/libata-core.c using
the ATA_HORKAGE_NODMA and ATA_HORKAGE_MAX_SEC_128 keywords and then
recompile the kernel.

2) Move the CD and DVD RW drives to a computer with another chipset to
determine whether they or the chipset are to blame.

Vlad
