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 sr0: Current: sense key: Medium Error 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?

sheesh 2.6.17 FC5, of course.
There is still something buggy, and I know this sounds obscure but I am not Guru enough to comprehend it all. But I have stated more than once that there is some kinda error in the kernel over sata where when I first loaded FC5 everything was regarded as /dev/sd* and now I get complaints where /dev/hd* isn't found, especially with the DvD.

The first thing on /dev/hda is my damn DvD, the second thing is a 200Gig harddrive, both almost brand new. When I boot, the boot from CDROM fails (correctly) and it goes to the harddrive and everything is cranking up like it ought to. Then it starts to fall apart looking for things that do not bear checking, like drive-ready on a Dvd. I didn't have this problem at first. Everything was
s m o o t h ... now it's blowing up. <--- technocrati speak, huh?
Once again, someone please point me to what file I need to eyeball to see where it's getting confused, so I can state this problem with a little but more correct verbage and not appear to be ranting like Grandma, "If you don't fix the problem you can't have any PUDDING!"
