FWIW I had to do "export PGCTLTIMEOUT=3600" before running the tests,
so that some of the tests don't timeout due to rpi4 being too slow.
As a side-note / PSA unrelated to your issue, the default u-boot you
get with the normal install results in somewhat poor performances on
rpi 4 (so far replicated on pi 4 B rev 1.5 and pi 4 B rev 1.4).
I'm seeing much better performances with the pftf/rpi4 thing.
It's more or less a 3x difference in synthetic cpu benchmarks
and about 2x on a kernel build (-j 4):
- 29m30s using the standard u-boot (overclocking settings are
here but they don't apply anyway): https://i.imgur.com/LzIoTYU.png
- 15m35s using pftf firmware without overclocking (so freq is
at the default 1500mhz): https://i.imgur.com/WzdQiPy.png
- 13m30s using pftf firmware with overclocking (2000mhz) and
over voltage: https://i.imgur.com/NsZV5FO.png
Something to maybe keep in mind if you ever make the switch, you'll
loose bwfm0 if you don't link that file:
$ cd /etc/firmware
$ doas ln brcmfmac43455-sdio.raspberrypi,4-model-b.txt
brcmfmac43455-sdio.openbsd,acpi.txt
Sorry for being a bit off-topic.
