I'm not sure if my direct replies are being caught in a spam filter. There were no instructions with the patch, which is 3 RPMs. I placed all three RPMs on the SD card for the Beagleboard XM. [Basically just do a save as with the sd card in an intel computer running opensuse.]
I booted the Beagleboard XM and ran all three patches, then rebooted. At that point I could no longer log into the Beagleboard XM. Not through the serial port or the "normally" (display driver and usb).
What is the output on the serial port (I mean from u-boot and then if you have something then)? Did you try a SSH login?
I have a program on the Beagleboard XM that I set up as a service that provides "telemetry" over a lan. That service was running since I coudl get data off the Beagleboard XM. I ran it for 3 days without a crash. [At that point I went to a different SD card / OS to work on other software.] The best I ever got prior to the patch is about 8 hours.
However, I think the performance of the software I was running was hampered by the patch since it seemed to be putting out less data. Since I couldn't log into the board, I have no way to analyze this.
So again, I am asking for someone to either explain how to apply the patch, or apply the patch to an image.
Install RPM kernel-omap2plus provided by Alex, using zypper and reboot.
As I stated before the JEOS wasn't booting on the Beagleboard XM. [The XFCE image works.] This might be a good way to get the bug out of JEOS and test the patch at the same time.
Try your patch on XFCE image first. One thing at a time. ;)
Since this appears to be a design flaw in the beagleboard XM, I'm sure all the board have an issue with this to some degree. My board is just worse than most. Thus I have a good test vehicle for the patched kernel, well provided I get one.
Thanks for your help in testing. Guillaume

Actually, I haven't tried the patch. The instructions are not detailed enough for me to use. The person who wrote has "issues" and isn't helpful. Let's leave it at that.
If anyone can explain in detail how to patch a kernel, I'm willing to try it.
I guess it's easiest if either Guillaume or me create a special kernel for you to try with that patch applied. I won't get to it before midnight today, but maybe can create one after that tonight that you can give a whirl. My Beagleboard XM is about 2 km away with lots and lots of snow lying in between me and it. :)
This is the 12.3 kernel + the patch you posted.
