Check Point L-50W: upgrade to 24.10 breaks wireless

I upgraded a Check Point L-50W device (actually, two of them) to 24.10 release. Following the upgrade, the wireless card doesn't initialize. Here are relevant lines from dmesg output:

# dmesg | grep ath9
[   15.674368] ath9k 0000:01:00.0: enabling device (0000 -> 0002)
[   15.698114] ath9k 0000:01:00.0: Failed to initialize device
[   15.703747] ath9k: probe of 0000:01:00.0 failed with error -95

The system information is as follows:

# ubus call system board
{
        "kernel": "6.6.73",
        "hostname": "L50WAP",
        "system": "Feroceon 88FR131 rev 1 (v5l)",
        "model": "Check Point L-50",
        "board_name": "checkpoint,l-50",
        "rootfs_type": "squashfs",
        "release": {
                "distribution": "OpenWrt",
                "version": "24.10.0",
                "revision": "r28427-6df0e3d02a",
                "target": "kirkwood/generic",
                "description": "OpenWrt 24.10.0 r28427-6df0e3d02a",
                "builddate": "1738624177"
        }
}

Downgrade to 23.05.5 resolves the issue.

If anyone has any ideas, I am all ears. If any additional information is required, I'll be happy to provide it.

Does 24.10 rc7 work?

No; same error message:

There is an ath10k issue in the release notes too, could it be related to the same issue? Issue reported here:

[https://github.com/openwrt/openwrt/issues/14541]

I have experienced this, too. It seemed fine for the few minutes I tried it, including Ethernet, but no Wi-Fi. Reverting to 23.05.5 and importing settings restored Wi-Fi.
