Status changed to 'Confirmed' because the bug affects multiple users.

[Cole Risch (metal-flow)]

failed during normal update preventing kernel build. Attached crash file.

I disabled the Netgear usb wireless device that needed these drivers in "Software and Updates" -> "additional drivers" tab and was able to build my kernel and use apt without issue.
