Hi @Jason,

Considering that the issue is reported on 6.1, which is an __LTS 
kernel__, any suggestion to fix this issue cleanly would help us a lot. 
Right thing here would have been propagating the changes from 6.6 (like 
for any stability issue), but considering the intrusiveness of them, is 
it even possible?

Just to be open about reproducibility of the issue, a bunch of them are 
reported, both internally and by customers.

Thanks
