Yesterday I've found a similar problem using 2.5.75. Trying to read a DVD
with a ASUS CD-S500/A the machine gives some errors in log then freezes.
>From log:
kernel: hdb: timeout waiting for DMA
kernel: hdb: timeout waiting for DMA
kernel: hdb: (__ide_dma_test_irq) called while not waiting
kernel: hdb: status timeout: status=0xd0 { Busy }
kernel: hdb: status timeout: error=0x00
kernel: hdb: drive not ready for command
kernel: hdb: ATAPI reset complete
kernel: hdb: cdrom_decode_status: status=0x51 { DriveReady SeekComplete Error }
kernel: hdb: cdrom_decode_status: error=0x30LastFailedSense 0x03
I've swapped the two conditions and after 5 "Bad Sector" the machine runs normally.
