Re: acpi issues on FreeBSD-current_r350103 on Thinkpad A485

Hi Jordy,

Thank you for your fast reply. Your links were very helpful.
As per the bugzilla report
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=231760, during the kernel
load screen I dropped to shell prompt and changed the boot params with
command
'set hw.pci.mcfg="0"

I was successful booting and installing FreeBSD from there. Hope it works
for you too!

Kind regards,
Cristian
