I just took the GENERIC kernel, modified one line to enable PAE and then
rebooted my i7 with 24G of RAM. I'm using NetBSD 7.0 i386. As soon as the
bootloader passes off to the kernel, it crashes and drops into the debugger.
Trying to do a 'bt' (backtrace) causes an instant-reboot.
So, I recompiled again and turned on all the debugging features. It didn't
crash this time and I was able to get a backtrace (once, but type it twice
and get another instant-reboot). I can transcribe what I saw on the screen
and file a PR if that's helpful. However, I'm curious:
1. Is this a known issue ?
2. Is this reproducible for anyone else ?
Not tried it with GENERIC, but with XEN3_DOMU I found that the actual RAM
you got was mod(4GB), so 3=>3, 4=>0, 5=>1, etc. Therefore every multiple
of 4GB (e.g. 24GB) failed to boot as there was zero usable RAM.
