What are the exact steps/their order, you do to trigger the bug? Can you also send me the whole dmesg output of a suspend/resume cycle? In case you can't catch the whole output due to the logs being swamped with the messages above, try setting log_buf_len kernel cmdline parameter to a higher value like 10M, for example. Thanks. -- Regards/Gruss, Boris.
