These symptoms appeared upon the first release of the 2.6.27 kernel
series in FC%, and are still present.
The problem is replicatable in more than one way, but here is how I do it:
Try to rip a CDROM or DVD.
I have tried three IDE drives, and one in a usb enclosure on two
different systems, and can produce the exact same errors. Therefore,
this is a real problem and not just me imagining that all my hardware is
going bad at the same time:
On any digital read of a CD or DVD, these messages start occurring, and
the read will 'hang' the device driver, forcing a reboot to recover.
Both mother boards tested have SATA connections.
1. ASUS-SLI Premium has SATA disabled.
2. DELL INSPIRON 9400 has the kernel parameter: combined_mode=libata
(without this, DVD playback is very very bad)
All tests on both systems with internal and external drives produced the
same results.
Here is a snippet from dmesg from an attempt using an external USB2
drive, thus eliminating the IDE driver from the equation:
usb-storage: device scan complete
sr0: scsi3-mmc drive: 62x/62x writer cd/rw xa/form2 cdda tray
sr 4:0:0:0: Attached scsi CD-ROM sr0
sr 4:0:0:0: SCSI error: return code = 0x8000002
sr0: Current: sense key: Medium Error
Additional sense: L-EC uncorrectable error
end_request: I/O error, dev sr0, sector 935072
Buffer I/O error on device sr0, logical block 116884
sr 4:0:0:0: SCSI error: return code = 0x8000002

Additional sense: L-EC uncorrectable error
end_request: I/O error, dev sr0, sector 935080
Buffer I/O error on device sr0, logical block 116885
Did I miss a bug report on this?
