How to debug this ? Any suggestion?

comment:9 by waddlesplash, 2 years ago

Unfortunately I don't really have any ideas. This seems to only happen consistently on Apple hardware, and may be due to memory corruption or any number of other things. Disabling SMP and running without ACPI are the first things to try. After that there is the kernel heap overflow checker, but that may not really help if the problem is in page memory structures...

Does this still happen on recent nightlies?

I was seeing similar crashes on my MacbookAir4,1. I gave disabling ACPI and SMP a shot; I could still reproduce the kernel panic with SMP disabled. Unfortunately disabling ACPI on this machine seems to make the entire USB not show up, so I can’t interact with the UI to test that configuration.
