al_06_3F contains the following:

 45 # 0x00000186 0x0000000000000000 # "IA32_PERFEVTSEL0 (Table: 2-29)"
 46 # 0x00000187 0x0000000000000000 # "IA32_PERFEVTSEL1 (Table: 2-29)"
 47 # 0x00000188 0x0000000000000000 # "IA32_PERFEVTSEL2 (Table: 2-29)"
 48 # 0x00000189 0x0000000000000000 # "IA32_PERFEVTSEL3 (Table: 2-29)"
 49 # 0x0000018A 0x0000000000000000 # "IA32_PERFEVTSEL4 (Table: 2-20)"
 50 # 0x0000018B 0x0000000000000000 # "IA32_PERFEVTSEL5 (Table: 2-20)"
 51 # 0x0000018C 0x0000000000000000 # "IA32_PERFEVTSEL6 (Table: 2-20)"
 52 # 0x0000018D 0x0000000000000000 # "IA32_PERFEVTSEL7 (Table: 2-20)"

All eight counters are identical and should refer to the same table.

The underlying issue is in msr-genie and likely affects many, perhaps all, allow lists.
