A head kernel rpi2 boot-hang bisected: -r326346 good; -r326347

[Andreas Schwarz]

I initially jumped from -r326192 to -r326726 and
ended up with a rpi2 that would normally hang
somewhere around release APs being displayed.
(I have had a couple of completed boots but many
dozens of hung-up attempts.) Both a debug kernel
and a non-debug kernel hang the same way.
Bisecting the kernel (holding world -r326726
-r326346 did not hang (nor did before)
-r326347 and later hung.

JFYI, the latest kernel (and world) running at one of my
RPI2-B is r326631, without any issues.

Interesting. (By the way: My context
is with a V1.1 Cortex-A7 based rpi2,
not V1.2 and Cortex-A53.)

Same here. The RPI2-B (not V1.2) is the most stable system of all my SBCs
running FreeBSD.

I've almost always run the root file
system being on a USB SSD instead of
on mmcsd0 . I wonder if that is
somehow involved since it may be
unusual. UFS file system.
The USB SSD is on a powered hub that
is in turn plugged into the rpi2.

Ok, I don't use an USB HDD, the limited USB bridge is the weakest point at
the whole rpi, so there are probably not much users with this setup. I understand
that you are forced to use ist
