Great! There are many reasons why that is important. You are right, this is a hardware bug, you can read more on : https://bugzilla.kernel.org/show_bug.cgi?id=109051
It should have been fixed in the 1.93 bios from Lenovo, but since they only support Windows, it may have been a combination of that and the driver, not sure. Personally I think any freeze is unacceptable, I would rather use a kernel parameter. But I find it very important that people who just install Linux do not encounter this bug, hence the big effort. I like Linux a lot and despite the challenges, the power of open source and motivation of people that make it awesome. The patch keeps the powermanagement better because c7 is still used. I will await your feedback because the kernel folks that push upstream will need some testing to get it in to the mainline kernel.
