Hi, Have read also other replays to this topic. I have seen-debug such deadlock problems with FPGA based PCIe endpoint devices (Xilinx chips) and usually (if not signal integrity problems), the problem was in wrong AXI master/slave bus handling in FPGA design. I guess you have FPGA Xilinx PCIe e

I am analysing a problem with I2C bus driver where the problem shows up as I2C bus completely blocked. The LX driver in question is /drivers/i2c/busses/i2c-xiic.c. Problem is difficult to reproduce, it happens very rarely. So far I saw that the main precondition is to have very heavy I2C traffic

Update: I2C bus driver TIMEDOUT because of PM autosuspend

I must update my report. It is not PM autosuspend (void calls do nothing, no miracle here). This morning I reproduced the I2C timeout error also with XIIC_PM_TIMEOUT=1 delay. For several days some other change was misleading me to PM autosuspend conclusion. What looks to me now is that j
