Tested by downloading nightly hrev57752 the KDL is displayed on the screen very slowly.

I think the only real possibility here is hrev57750~2. Strange that it would cause this. Another user on IRC commented about the boot succeeding but redraws being very slow.

Ah, the problem is likely that vm_init_post_modules is called after we clear the arrays: ​https://xref.landonf.org/source/xref/haiku/src/system/kernel/arch/x86/arch_vm.cpp#700

Oddly enough the problems (slowness and KDL) don't replicate on VMware at all.

This should be fixed in hrev57753, please retest.

Thank you for the quick turnaround on this!

I can confirm that it is resolved on all my machines with this change. Verified on a Lenovo T450, iMac 27" 4x i5, and on a 2x Quadcore Dell T7400. Good work!

Indeed, updating to hrev57753 boots and works as expected.
