Yes! I can confirm that these two patches made me able to boot a
Debian unstable from a USB stick on an Odroid C1+ for the first time.
I tested both a v4.13.2 kernel and a v4.14-rc1 with the SMP
I'm having one oddity with the stress-ng tool though: Several
filesystem related tests make the Odroid hang for me. This works for
$ cd /tmp/; time stress-ng -v --class filesystem --sequential 1 --exclude copy-file -t 30s
(with /tmp being a tmpfs)
Those tests make the system hang for me almost immediately, though:
$ cd ~/; time stress-ng -v -t 30s --chdir 1
$ cd ~/; time stress-ng -v -t 30s --dir 1
$ cd ~/; time stress-ng -v -t 30s --dirdeep 1
$ cd ~/; time stress-ng -v -t 30s --fallocate 1
$ cd ~/; time stress-ng -v -t 30s --mknod 1
$ cd ~/; time stress-ng -v -t 30s --sync-file 1
$ cd ~/; time stress-ng -v -t 30s --xattr 1
Unfortunately, there is no error message on my serial console
then, it just hangs silently with the heartbeat LED stopping to
I also tried:
* Using a USB connected hdd instead of the USB flash drive, with
an actively powered USB hub in between.
* Using a clean v4.13.2 with the patched v4.14-rc1 DTB file
instead of v4.14-rc1 kernel (with the SMP patches included).
Both without success. I also experienced a two freezes while
apt-get installing a few patches.
Anyone having an idea how I could make those crashes more
verbose or what else I could try? Or could it be that it freezes
so silently due to some sort of internal power issues? (I got a
little paranoid with power stuff since the confirmed,
hardware related power issues on the Odroid U3)
