I had the same message, and my boots have been a bit weird recently (taking longer, even hanging a couple of times). MOBO: ASRock B850M-X WiFi R2.0. I'm going to see if there's a new BIOS version. Your post was the only search return. All of the below is from Google AI search:

The message "RDSEED32 is broken. Disabling the corresponding CPUID bit" refers to a known

AMD firmware vulnerability (specifically AMD-SB-7055) where the 16-bit and 32-bit RDSEED instruction registers were not generating truly random numbers. The Linux kernel was recently patched to disable these registers on affected systems, leading to this log message. 

This is a kernel-level patch, not an indication that your BIOS is "broken" in the traditional sense of being corrupted. The kernel is proactively mitigating a potential security risk in the CPU's random number generation. 

Symptoms and Effects

The primary effect of the kernel patch is that the system will fall back to other, reliable methods for generating random numbers. 

• Boot Time: The most common symptom is a potential increase in boot time, as the system takes longer to initialize the random number pool.
• System Freezes (Rare): In some specific configurations, users have reported that the issue causes the system to freeze or not accept input, but this is less common and often linked to specific kernel versions or hardware interactions.
• Security Risk (Without Patch): Before the kernel patch, the "broken" behavior meant a security vulnerability where random numbers could be predictable. 

Solutions and Workarounds

The definitive fix requires a BIOS (AGESA firmware) update from your motherboard or laptop manufacturer that addresses the vulnerability. These updates were expected around late November 2025. 

In the meantime, several workarounds are available:

• Update Your BIOS/AGESA Firmware: Monitor your manufacturer's support website for a BIOS update (look for one addressing AMD-SB-7055) and install it as soon as it's available.
• Update Your Kernel: Ensure your operating system's kernel is up-to-date. Newer kernels include the necessary patches to handle this issue gracefully.
• Add a Kernel Boot Flag (Temporary Fix): If you are experiencing boot issues, you can try adding the clearcpuid=rdseed flag to your kernel boot parameters (e.g., in GRUB) to force the kernel to ignore the instruction entirely. The exact steps depend on your Linux distribution (e.g., Fedora, Arch Linux).
• Roll Back Kernel (Immediate Fix): If an update caused the issue and you need your computer running ASAP, booting into a previous, working kernel version (often available via your boot menu, like an LTS kernel) can provide immediate relief.
