Comment 32 for bug 1437353

Well, the CI part confirms that there is no regression, but there is as yet no indication that the issue is fixed aside from the cases where firmware was updated (but then, it's not the SRU).

There's still a need to verify the fix positively on affected hardware.

Now, KingJ's comment says that testing has been done with the version of grub in bionic, and with the version of grub being SRUed to xenial, and neither did work. I think that qualifies as verification-failed, and we'll need to have another look at grub's behavior. At this point, there is no obvious patch missing, and we'll need to debug using packet captures to try and make sense of it.
