Hi Joel,
May I have your attention for one AST driver bug, which is detected on Intel Emerald Rapids Server.
The bug is reported on Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=217278
The issue can be reproduced on both mainline v6.1 and mainline v6.3-rc4
Here is the description:
ast driver will trigger unrecoverable kernel panic during S4 resuming.
If add "modprobe.blacklist=ast" kernel parameter to disable ast driver
Can avoid the kernel call trace.
