Package: li1nux Version: 4.19.0-17 tl;dr: I have a feeling this is https://bugzilla.redhat.com/show_bug.cgi? id=1656233
After resuming a buster system with linux-4.19.0-17 on a thinkpad x220 the intel 6205 wifi fails to work, with the below dmesg warnings. Hopefully this _is_ just the same bug as linked, which would suggest the solution is https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/ linux.git/commit/drivers/pci/probe.c? id=10ecc818ea7319b5d0d2b4e1aa6a77323e776f76 [11218.145442] iwlwifi 0000:03:00.0: Error, can not clear persistence bit [11218.145448] iwlwifi 0000:03:00.0: Failed to start HW: -1 [11218.145454] iwlwifi 0000:03:00.0: Unable to initialize device.
