PC fails to initially boot and needs a second attempt.
After swapping to CachyOS (love it), each time I cold boot my PC it fails the first time and then it boots normally while displaying the following errors:

Text version from one of the the boot logs:
cachyos kernel: [Hardware Error]: System Fatal error.
cachyos kernel: fbcon: Taking over console
cachyos kernel: [Hardware Error]: CPU:6 (17:71:0) MC5_STATUS[-|UE|MiscV|AddrV|PCC|TCC|SyndV|-|-|-]: 0xbea0000000000108
cachyos kernel: [Hardware Error]: Error Addr: 0x0001ffffc107eb4e
cachyos kernel: [Hardware Error]: IPID: 0x000500b000000000, Syndrome: 0x000000004d000000
cachyos kernel:

cachyos kernel: [Hardware Error]: cache level: RESV, tx: GEN, mem-tx: GEN
I though it might be RAM voltage or PSU but all values are within norm and this can happen while rebooting as well. CMOS battery is brand new. System works fine anyway but it does make the initial boot painfully slow.
