Subject[BUG] ATAPI command TEST_UNIT_READY never succeeds!
Hi,
Do you ever noticed that the ATAPI command TEST_UNIT_READY always
fails to execute !?
I debugged in the following environments:
piix + Intel ICH6/ICH7 PATA
atiixp + ATI SB600 PATA
libata + ata_piix + Intel ICH6/ICH7 PATA
libata + sata_sil24 + Silicon Image 3132
libata + ahci + ATI SB600 SATA
libata + ahci + Intel AHCI
but none of them can execute TEST_UNIT_READY command successfully.
For example, in ahci driver, ahci_interrupt() reads port status as
0x4000_0000, which indicates an taskfile error.
