Seems par for the course with Dell lately. My XPS has a Wifi+ACPI firmware bug, wherein when the wifi says, hey can i go into power save mode, and the ACPI grabs its ankles, kernel panic! For years I thought It was a linux thing but after stumbling on the motherload of complaints im saddened. Its been my first linux laptop and its sad to see that the shortcommings had nothing to do with distro, rather hardware regression. Theres no plans to fix either. Luckly it happens maybe twice a year.

It’s pretty much the same on windows. It’s not an ideal workaround but I recently turned of C-states in the BIOS and since I’m always plugged in anyway, it seems to have stabilized a bit.

It seems to be connected with the WIFI card and the machine going to sleep. People have had their entire motherboards replaced and it hasn’t solved the problem. It’s annoying because I spent a lot of money on my XPS and it’s basically junk.
