The fix for Noble (0ubuntu2.23) appears to be missing the iwlwifi-bz-b0-gf-a0
firmware variant. The package includes iwlwifi-bz-b0-gf-a0 up to version 96,
but kernel
6.17.0-14-generic (HWE) requires minimum version 98.
System details:
- Ubuntu 24.04 Noble, kernel 6.17.0-14-generic (linux-generic-hwe-24.04)
- linux-firmware 20240318.git3b128b60-0ubuntu2.23
- PCI device: 8086:7740, detected as Intel Wi-Fi 6E AX211 160MHz
dmesg output:

WiFi works on kernel 6.14.0-37-generic but is completely broken on
6.17.0-14-generic. The bz-b0-fm-c0 variant was updated to version 101 in this
fix, but bz-b0-gf-a0 was not updated
beyond 96.
