Comment 13 for bug 1929902

Hi @chaoqin,

I can't find the device "8086:4b7e", I have also tried the mainline kernel v5.14-rc6 but no luck.

I also tried to boot into the UEFI shell and use the 'pci' command to list the devices, but still no luck. [1]

Do I need to enable some settings in BIOS so that I can see the device "8086:4b7e"?
Thanks!

BIOS version: EHLSFWI1.R00.3044.A01.2101210945
