Hi,

I can’t find any mentions of these faults

what could be the source?

Many thanks

Not sure for your case, but if you have a task that can hog the GPU for some time and can afford a frozen GUI, you may try:

sudo echo N > /sys/kernel/debug/17000000.gv11b/timeouts_enabled

hello cdevd,

may I know what’s the actual use-case, please share the detail steps to reproduce the failure.
thanks

Hi JerryChang

Just running Deepstream,
2 x axis p7304 encoders connected via netgear network switch
HDMI, keyboard and mouse go through a KVM

no other peripherals connected

here’s a dmesg from the unit in case that shows something

Thanks

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

hello cdevd,

I don’t see gk20a failures from the attach logs.
could you please share which nvpmodel you’re running, i.e. $ nvpmodel -q
also, how long did you reproduce the failure.
thanks
