--- Comment #17 from Arie Bikker <src-2...@bikker.homeunix.net> ---
(In reply to pete from comment #7)
Can confirm a repeatable malfunction on warm booting from another OS (Windows)
System: Thinkpad X1 Yoga 4th (20QF), bios version 1.41 (2020-10-27)
iwm dmesg after warm reboot from windows:
iwm0: <Intel(R) Dual Band Wireless AC 9560> mem 0xea338000-0xea33bfff irq 16 at
device 20.3 on pci0
iwm0: fw chunk addr 0x404000 len 712 failed to load
iwm0: iwm_pcie_load_section: Could not load the [0] uCode section
iwm0: iwm_start_fw: failed 60
iwm0: Failed to start INIT ucode: 60
iwm dmesg after full power down:
iwm0: <Intel(R) Dual Band Wireless AC 9560> mem 0xea338000-0xea33bfff irq 16 at
device 20.3 on pci0
iwm0: hw rev 0x310, fw ver 34.3125811985.0, address 84:c5:a6:29:b6:02
My haunch is: "Bios Bug". Probably windows loads firmware that prevents the
next load by FreeBSD after warm reboot. Shouldn't windows's firmware load been
undone by the BIOS during reboot?
If so, this is strictly not a FreeBSD driver issue (although I would be happy
if some fix arrived ;)
