[Kernel-packages] [Bug 2056718] Re: openvswitch gentling validation warning: missing .resv_start_op
This bug is awaiting verification that the linux-
bluefield/5.15.0-1039.41 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-jammy-linux-bluefield' to
'verification-done-jammy-linux-bluefield'. If the problem still exists,
change the tag 'verification-needed-jammy-linux-bluefield' to
'verification-failed-jammy-linux-bluefield'.
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. Thank you!
