Is there any way to be make it sure? I can't remember well, but PRINTING warnings could well had been the reason. Try my patch, and see if suppressing the printf's themselves could save the CPU. If not, well, it could be scheduler related, and you might want to try 4-stable instead. IIRC, my system was working without any noticable load while the logging was turned off (using my patch). I don't remember well about how loaded it was with the logging turned on. Oh, here I found a note I wrote back then. It reads: Updateing the BIOS changed this 'error' rate. On P2B-DS, The original BIOS with 4.5-PRELEASE kernel panic'ed. BIOS 1.13 beta 1 gave some 12 err/sec rate where as BIOS 1.13 beta 7 gave 0.9 err/sec. See if your BIOS is most recent as well.
