Hi All, I am working on a mobile development platform and performing some stress warm boot tests using UART debug console(which is using serial 8250 driver for console).
I am getting device debug console UART RX hang after iterations > 1500. after this issue am not* able to issue any command. Able to see logs though. Later I kept some debug prints in isr and able to see that device is able to generate interrupts when some data is received. So I came to conclusion that some malfunctioning is happening in upper layer not sure which layer has this problem. Can some one give some ideas at which layer I can check? One more observation is when I perform a open and close calls on debug UART port(in my case ttyS0) while device is in UART RX hang state, then I notice the UART console RX again below active and able issue commands from UART console itself.
