Hi,
I'm announcing the release of the 6.6.28 kernel.
All users of the 6.6 kernel series must upgrade.
The updated 6.6.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-6.6.y and can be browsed at the normal kernel.org git web browser: https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git%3Ba=summa...
Linux 6.6.28 failed to boot with the following panic *1 on a server with mellonax CX-6 VPI NIC, but 6.6.27/6.1.87 boot well.
After reverting 'net/mlx5: Restore mistakenly dropped parts in register devlink flow', linux boot well.
there is a similar discussion in net-dev ML[1]. In short, it seems this patch is missing from stable, which is prerequisite for the bad patch: 0553e753ea9e "net/mlx5: E-switch, store eswitch pointer before registering devlink_param".
Wang, can you test it out please?
After apply "net/mlx5: E-switch, store eswitch pointer before registering devlink_param" to 6.6.28, linux boot well here.
and "net/mlx5: Restore mistakenly dropped parts in register devlink flow" is NOT applied here.
Thanks a lot.
