I use Fedora Rawhide with default kernel and firmware packages.

$ uname -r
5.16.0-0.rc6.20211223gitbc491fb12513.44.fc36.x86_64
$ rpm -q linux-firmware
linux-firmware-20211027-126.fc36.noarch

By the kernel logs, it looks like this:
After reboot:
$ dmesg | grep mt7921e
[ 8.629358] mt7921e 0000:05:00.0: enabling device (0000 -> 0002)
[ 8.630229] mt7921e 0000:05:00.0: ASIC revision: 79610010
[ 9.687652] mt7921e: probe of 0000:05:00.0 failed with error -110

# rmmod mt7921e
# modprobe mt7921e

[ 215.514503] mt7921e 0000:05:00.0: ASIC revision: feed0000
[ 216.604741] mt7921e: probe of 0000:05:00.0 failed with error -110

After cold boot after shutdown:
$ dmesg | grep mt7921e
[ 8.545171] mt7921e 0000:05:00.0: enabling device (0000 -> 0002)

It looks like something is not re-initialized after a reboot.
Laptop BIOS is latest: Version 316

Maybe anyone from the pci mailing list can lid some light why pci
device not re-initialized after a reboot?
