asus-grouper: device reboots spontaneously under heavy load
My Nexus 7 (asus-grouper) seems to reboot spontaneously on latest PostmarketOS master
whenever there's substantial activity. I have verified that this happens both at the command line and in weston
. Steps to reproduce:
At the command line:
# setup wifi networking (you'll need the latest master for this)
$ sudo ip link set p2p0 down
$ sudo rc-service wpa_supplicant stop
$ wpa_passphrase <your ESSID> <your password> > ./wpa_config
$ sudo wpa_supplicant -B -Dnl80211 -iwlan0 -c./wpa_config
$ sudo udhcpc -i wlan0
# attempt to install a package with many dependencies
$ sudo apk-update
$ sudo apk add postmarketos-ui-i3wm
In weston
:
- start a bunch of demos simultaneously ("smoke test" is especially effective)
The device does have a /dev/watchdog
, but installing watchdog-kick
, or increasing the value of tegra_wdt.heartbeat
in the kernel command line has very little effect.
After reboot, /proc/last_kmsg
contains the following:

I don't know if this might be just a hardware issue on my device (it has seen a lot of use over the years) or the fact that the flash IO is terrible (arguably one of the reasons Google abandoned the device just a year after its launch). I'd love if someone could try and reproduce this or give some pointers to debug this further.
