Interesting
On Linus's kernel we don't panic, but we see this below
I will reboot one more time, validate same behavior and then try the
rdma tree
I am pretty sure there are changes in that RDMA tree that piggy back on
the below scenario to trigger the panic.
And I know Bart you have the RDMA stuff pulled in to yours.
If needed I can capture a vmcore to fully triage the panic.
Rebooting.
