Summary: attempting to read scuffed CDs causes libata to switch
the drive to PIO0 mode and there's no way switch back
Product: IO/Storage
Version: 2.5
KernelVersion: kernel-2.6.25.14-108.fc9.x86_64
Platform: All
OS/Version: Linux
Tree: Fedora
Status: NEW
Severity: normal
Priority: P1
Component: IDE
AssignedTo: [email protected]
ReportedBy: [email protected]
Attempting to rip a scuffed CD results in lots of errors in the log as libata steps down from UDMA66 to PIO0 (for no reason, afaik, these are media errors, not link errors). Once the libata has erroneously decided on a tediously slow communication method, there's no way to tell it to go back to UDMA66.
