SYNC_INVALID_EL1h exception #20

Closed mcribbs closed 1 year ago

mcribbs commented 2 years ago

We're randomly getting a SYNC_INVALID_EL1h exception when running in QEMU. The time before this occurs is not consistent. Checking older commits this seems to have existed for quite some time.

SYNC_INVALID_EL1h (type 4), ESR: 0x8a000000, ELR: 0x0000000060000345, SPSR: 0x60000345, EL: 1

Reproduced on Pi400.

Another run in QEMU results in

SYNC_INVALID_EL1h (type 4), ESR: 0x8a000000, ELR: 0x0000000020000345, SPSR: 0x60000345, EL: 1

Note the ELR address value is different 0x0000000020000345 vs 0x0000000060000345

And a pi400 run with ELR of 0x0000000080000345
