As expected 5.11 did crash. Unfortunately the vmcore is not useful as it
filled up disk space so it is incomplete and I had to remove it to free
up some space.

BTW
For 5.11 (or oem-5.10 on Focal) it has only 3914d88f7608e6c ("xsk: Respect
device's headroom and tailroom on generic xmit path") applied, so I expect you
will see this issue with it.
For anything older than 5.10, none of these four patches were applied.

Thanks for looking into this. I will try edge HWE. I did try it week or
two ago but it was still at 5.8. I will need to let the 5.11 kernel run
for couple of days to be sure that it is properly fixed.
Btw the same problem also exists on 5.4 kernel line. I do not have vmcore from
that kernel versi
Considering the complexity of these and the fact that 5.8 is missing other
vital parts to get these applied, e.g.:
* f09ced4053 xsk: Fix race in SKB mode transmit with shared cq
* 1c1efc2af1 xsk: Create and free buffer pool independently from umem
I think it's quite unlikely to get this fix

I think this patchset is the fix:
