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 [39dafcc](https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=39d6fcc73100ae4aeeec0194bbf102c672673edd), not sure at the moment) gets past the splash screen but that's where the soft lockup starts to happen.
