** Summary changed: - Intel-microcode 3.20250211.0ubuntu0.20.04.1 causes panic and bootloop + Intel-microcode 3.20250211.0ubuntu0.20.04.1 causes panic and bootloop on Dell PowerEdge R740xd
** Description changed: After updating intel-microcode from 3.20241112.0ubuntu0.20.04.1 to 3.20250211.0ubuntu0.20.04.1 in my Ubuntu Server 20.04.6 LTS the server is stuck in a bootloop. Sometimes I can see an error on console while booting, or sometimes it reboots without completing bootup sequence, and is no more usable. For what I have seen on console, it appears to be a kernel panic error coming from "tg3" (broadcom Tigon3 Ethernet driver for NICs). Now I succeeded in reverting to version 3.20241112.0ubuntu0.20.04.1 thanks to recovery mode, and server is booting and stable again. I put the package on hold to prevent upgrading.
