Comment 70 for bug 818830

Potentially bad news: I started experiencing freezes again on my X220 with RC6 enabled and the new (tunable RC6) kernel. The freezes only occur (so far) while using LibreOffice Calc, but they are exactly the same types of freezes I have experienced with RC6 before. I have not yet seen the graphical glitches appear as they used to, so that's good news at least. I can't be 100% sure these freezes are related to RC6 and not to LibreOffice Calc, so I'll keep testing, but I suspect that they may be linked to RC6 since I never had a problem with Calc before. I will report back. I would recommend that anyone testing RC6 should use their computer extensively for several days before reporting anything.
