Public bug reported: [Summary]
During the SRU testing, I found a Lenovo workstation has multiple NICs installed that failed to wake up from cold-reboot by rtc event. After some investigations, I found that it's because too many kernel message appear and slow down the power off. We don't have any connection on those impacted NIC, so we still can access the machine, but I assume it should also be a regression for 6.8 kerenl. Those error messages didn't be recorded by journalctl, so I just took a photo and converted them to text. [Expected result] SRU test can continue after cold-reboot [Actual result] Cold-reboot takes too long to power off that exceed the wake up time we set for rtc.
