#9101 new bug

CDDA tries to send opcode 0x43 (CD READ TOC) to hard disks

Reported by: x-ist Owned by: bga
Priority: low Milestone: R1
Component: File Systems/cdda Version: R1/Development
Keywords: Cc:

Has a Patch: no Platform: All

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
