Hi, I'm currently testing -current snapshots (tagged 5.8-beta) on an hp dl320 gen8 and the machine panics with the following message:
panic: null acpicpu Stopped at Debugger+0x9: leave If i boot with an older kernel (5.7 -current snapshot) and disable acpiprt (via config -ef /bsd) the system no longer panics at that stage,the following messages occur: ehci_sync_hc ciss0: unqueued ccb 0xffffff0001bbbc00 ready, state=10<POLL> dmesg below is obtained running a 5.7 snapshot as i'm unable to boot system and get it under
