Hi Huang,
The original system needs to ship to our customer ASAP. Disabling ghes is sufficient for the time being for that. As such, I have set up an identical system as a temporary master for another cluster to continue this testing.
I have applied your patch. Here is the output of dmesg | grep GHES so far:
[ 9.272198] GHES: gar mapped: 0, 0xbf7b5ff0 [ 9.280782] GHES: gar mapped: 0, 0xbf7b6200 [ 9.285102] [Firmware Warn]: GHES: Poll interval is 0 for generic hardware error source: 1, disabled.
I have the serial console activated and stress tests started back up. I'll reply with the output once I get another panic.
Thanks! Rick
