Hi,
A changed was added to both version 5.17.5 and 5.15.36 which causes my computer to freeze when resuming after a suspend. This happens every time I suspend and then resume.
I've bisected the change to commit: cbe6c3a8f8f4315b96e46e1a1c70393c06d95a4c (net: atlantic: invert deep par in pm functions, preventing null derefs)

My computer details that might be relevant:
OS: Arch Linux
CPU: AMD 5950X
GPU: AMD 6800XT
As expected I have an Aquantia ethernet controller listed in lspci:
05:00.0 Ethernet controller: Aquantia Corp. AQC107 NBase-T/IEEE 802.3bz Ethernet Controller [AQtion] (rev 02)
Please let me know if there is any more info I can give that will help.

Just a quick note that I have the same issue (same card model); since recently
(5.15.36) the hang after resume is 100% reliable. IIRC it used to be hit-and-miss
before that. I'm currently building .38 with the mentioned commit reverted and
will report back. Thanks for bringing this up.
With said commit reverted and 5.15.38 I got 1 successful resume and 1 lockup.
Difference is that with the patch reverted, the locked-up system can be pinged
(unlike with the patch applied), though resume still does not finish properly and
now probably runs into the problem that the patch was trying to fix.
Any network services like ssh are still dead though.
This used to work every time, all the time..looks like I'll try removing the
module before suspend.
