#9101 new bug
CDDA tries to send opcode 0x43 (CD READ TOC) to hard disks

Description
Installed from nightly image hrevr1alpha4-44654.
The syslog shows occasional
KERN: ahci: AHCIPort::ScsiExecuteRequest port 0 unsupported request opcode 0x43
followed some lines later by
KERN: read_pos(pos:1153735598080, len:512) failed with: 0xffffffff
Don't know whether those are related to each other. The ahci functionality seems not to be affected - works like a charm, but maybe someone is interested in knowing that.

This is not a bug in the ahci driver. The CDDA file system is sending opcode 0x43 (read CD-ROM TOC) to the hdd. The disk on ahci port 0 size is 640.135.028.736 bytes. The UDF file system is trying to read data at: 1.153.735.598.080 246.085.519.941.632 297.285.288.206.336 863.393.653.227.520
