Hi,
After upgrading kernel from 4.14.40 to 4.14.88,I found that 'HP FlexFabric 10Gb 2-port 554FLB Adapter' device is not in use. There are erros in dmesg log.
The Server is 'HP FlexServer B390'.

At the beginning, I thought the lpfc driver itself is the cause of the error.But,the error is still seen when 'lpfc driver' updates to the latest version.
To find the root cause and fix it, we checked the kernel version from 4.14.41 to 4.14.88, built and tested the kernel for booting.
The commit that caused error after bisect is ef86f3a72adb8a7931f67335560740a7ad696d1d,when I removed the commit the issue went away.
Commit info:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-4.14.y&id=ef86f3a72adb8a7931f67335560740a7ad696d1d
During the test, I also found another issue that the system of 'HP FlexServer B390' server failed to boot by "hpsa driver timeout",basically, looks like the hpsa didn't detect the hard drives and udevd is stalled.
After upgrading from v4.14.54 to 4.14.55, hp system didn't boot ,but the system is ok when using the v4.14.55 kernel that has removed the commit.
The commit of ef86f3a72adb8a7931f67335560740a7ad696d1d also affects the HP Smart Array P220i RAID device.Because the v4.14.88 kernel is ok, I think that subsequent commits may have fixed the hpsa driver issue, but lpfc driver issue is not.
If there is any more info I can provide, just ask what would be useful. Any suggestions?
Thanks
Liang
