Summary0017598: Any kernel beyond 8.0 rescue fails to boot
DescriptionHardware : SuperMicro MBD-H11SSL with AMD Epyc 7502 32-core CPU

Originally installed CentOS8.0.1905 on this system. / and /boot are on real GPT partitions, data disks are a combination of LVM and sodftware RAID-5.

Regular yum upgrades to running system since February all ok but a recent power outage lead to trying to boot from 8.2 kernel ( 193.6.3 ) which failed. After a lot of trial and error I determined that the only kernel that would boot properly was the original ( 147 ) rescue kernel and initramfs. For any other combination I get a black screen immediately after the Probing EDD .... message and the hardware eventually reboots. Removing quiet and rhgb , gives no extra output on the screen, rebuilding initramfs with either -a rescue or -H does not make any difference, adding and/or rd.break to get a dracut shell doesn't do anything, ading init=/bin/bash doesn't do anything either,setting edd=on or off makes no difference. Removing and reinstalling kernels make no difference.

 So - basically the boot fails at a very, very early stage and I'm not sure how to get mode debug output. Any suggestions to other kernel options to try ? Like how to select the most basic video ? What is the dumbest VGA mode one can select ? Any early boot debug parameters ? Any other modules that I should try to load in to initramfs ?

This is obviously some weird combination of software and hardware ( BIOS ?) that causes booting to fail. Highly unexpected.

The BIOS is set to legacy ( ie. non UEFI only ) but I don't think there is anything wrong with with it or grub2 for that matter. I can do an "ls" at the grub prompt for all the partitions on all disks and they appear to be correct. Using (hd0,gpt... ) insted of labels or /dev/sda... makes no difference.

Booting from an 8.2 install USB fails too by the way.

Steps To ReproduceBoot anything beyond the 8.0 rescue kernel.

Could be a video driver problem with the built in ASPEED card and the linux ast driver according to this link .
