A few bits of information are missing from that PR, it would be useful if you could add the following to it: - A full verbose dmesg - two outputs of "vmstat -i", say 10 seconds apart, both before and after the problems start. FWIW, I'm not convinced that your problem is the same as the submitter's problem - he's complaining only on issues when he hits the last block of the CD, and you're having problems with slow reads throughout the whole CD. If you're not using a "JMicron JMB363 SATA300 controller" it's likely your issue is different to kern/133122 and it would be worth creating a new PR with a full description of exactly what symptoms you see, and the above information.
