[TLDR: This mail in primarily relevant for Linux regression tracking. A
change or fix related to the regression discussed in this thread was
posted or applied, but it did not use a Link: tag to point to the
report, as Linus and the documentation call for. Things happen, no
worries -- but now the regression tracking bot needs to be told manually
about the fix. See link in footer if these mails annoy you.]

I have a Supermicro X10SRA-F/X10SRA-F with a ConnectX®-5 EN network
interface card, 100GbE single-port QSFP28, PCIe3.0 x16, tall bracket;
MCX515A-CCAT

When booting a v6.3+ kernel, the boot process stops cold after a
few seconds. The last message on the console is the MLX5 driver
note about "PCIe slot advertised sufficient power (27W)".

bisect reports that bbac70c74183 ("net/mlx5: Use newer affinity
descriptor") is the first bad commit.

I've trolled lore a couple of times and haven't found any discussion
of this issue.
