Artem, is this issue still happening? I still have it in my list of
regressions. Side note: I accidentally noticed people continue working
in the area that 84676c1f21e8 touched;  see
https://marc.info/?l=linux-block&m=152021971313902&w=2 ("[PATCH V2 5/5]
genirq/affinity: irq vector spread among online CPUs as far as
possible"). I wonder if that might be related in any way. Ciao, Thorsten
