I applied the patch as you proposed without problem. I attach the kernel logs of the past few days. As far as I can see, with the patched kernel errors appear only under heavy load . If you want, I could provide a (temporary) ssh-login to my machine. Maybe it would make it easier for you to debug the problem. If you want to use it, I need your public ssh-certificate and your login-name and I would send the login-details to you. Thanks again, yours Kasimir.
