Re: install/55478: netbsd 9.0 - Installer freezes on macbook pro late 2013

Yes, it is haswell, since the i7-4850HQ CPU is visible in dmesg. Maybe
the output of the model should be changed to 0x46 to avoid confusion?
And perhaps CPU error is irrelevant, since the boot was performed
without ACPI.

Back to topic, my mac mini is also Haswell based but on a bit
different chipset Lynx Point-LP instead of Lynx Point, thus my xhci
device is 0x9c31 while this macbook pro seemingly has 0x8c31. In my
case, I don't seem to have any issues with USB3 devices. I found only
one bug related to this device which sounds similar a bit -
kern/49076, but it apparently was fixed. Nevertheless, I don't think
that it needs any special treatment compared to LP version. I can't
find anything in FreeBSD code for example. Probably something specific
to the particular laptop model...
