Not always, but more often than not. I am running 32-bit but have used 64bit prior. I reinstalled my system thinking that it was a problem with 64-bit libraries. The full lsmod is on the bug report. I am currently running fine again. I will keep my laptop on throughout the day in the hopes that it goes down. Let me know if you need anything else.
