I did have some kernel panic lately and today after upgrading to 11.5 I got a different message

CPU Machine Check Architecture Error Dump (CPU: UNKNOWN, CPUID: 0x80000009000A0653)

If is an hardware issue is not that easy understand what could be since I use a Wacom tablet, and have several disk connected
I also have 2 slot with Crucial RAM that I add when I bought the iMac last year

Any way to understand what was referred that CPUID when kernel panic happened?
Or any software to test just the RAM?
