softlockup

Updating linux-firmware to the latest git version causes my pc to lock up
during boot. I have a 3900x paired with a 7900xtx running arch linux with 6.3.4
xanmod kernel (but this happens with kernel from the core repo as well) and
mesa 23.1.1 if that matters.
During boot time I see the following error printed and the system is completely
locked up, only hard reset helps:
`May 31 07:20:40 valhalla kernel: watchdog: BUG: soft lockup - CPU#5 stuck for
26s! [swapper/5:0]`

accompanied with a lots of amdgpu errors in the journal (followed by stack
trace after both):
```

The issues start to happen after [this commit,
ffe1a41e](https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=ffe1a41e2ddbc39109b12d95dcac282d90eba8fc)

but not the above mentioned soft lock, instead after initramfs loads I get the
bios splash screen back and it's stuck there.
There are different amdgpu errors(followed by stack trace) during this:
```

```
Logs during this in "amdgpu_error"

Note that at the end it seems like the system is running but as I only saw the
bios splash screen rebooted via sysrq/reisub.

The commit after ffe1a41
([56832557](https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=568325574a3b6148f3296984aa24fcd1fb4b912c)
or might be the one after that

not sure at the moment) gets past the splash screen but that's where the soft
lockup starts to happen.
