I believe that a number patches have just been backported for usbnet: 
smsc95xx for 5.15 and 5.18 that might resolve your issue.

I did find another crash:

DMA-API: xhci-hcd xhci-hcd.1.auto: cacheline tracking EEXIST, > > > 
overlapping mappings aren't supported But it appears happens in the hub 
code as other hubs then smsc95xx also have that error. This one has not 
yet been resolved.
