This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- eoan' to 'verification-done-eoan'. If the problem still exists, change the tag 'verification-needed-eoan' to 'verification-failed-eoan'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

Lowest risk for other platform/driver "[Bug Description] Currently, up/down port process may concurrently operate timer(del_timer_sync/add_timer_on) with setting IRQ affinity, and cause system breaking down. [Steps to Reproduce] set misc irp affinity of PF during up/down port by follow script: while((1)) do for i in {0..31}; do echo $i > /proc/irq/678/smp_affinity_list; done done while((1)) do ifconfig eth4 down ifconfig eth4 up done [Actual Results] System break down. kernel call trace [Expected Results] System run normally.
