I can't think of any relevant change which can cause this and I doubt it's something affecting many machines given that you're currently the only one reporting this problem. Any chance it's a hardware fluke? Can you please make sure it doesn't happen with 2.6.27? > Unless you can think of anything else, I'm just going to wait and see if > a commit in .29 will fix the problem. Eh... I doubt that will happen. No scheduled change for SFF HSM implementation.
