Care to specify what linux version you are testing against?
Does it hang in idle always immediately on booting?
Or does the serial console first hang with sysrq still working (ctrl-a h in minicom for help) with device eventually locking up hard?
I just posted an updated patch Alex on other thread. Attaching here again for your reference. Please try it out and see if the you still get a hang.
it does not hang this time.
This is good news and exactly what I expected.
but I am not sure it can solve my problem, since RCU stall is not easy to reproduce in short time.
You may want to run the system longer if you can. I suspect the RCU stall was also side effect of missing interrupts.
Sure. it do remove the RCU stall on my panda board.
Thanks for confirming. Tony already send fix upstream so it should show up in next rc mostly
