We recently changed out test configs to use CONFIG_INIT_STACK_ALL_PATTERN=y (my fault) and the documentation says that 0xaaaaaaaa is the default uninitialized variable pattern for Clang 64bit. So it's possible that this is not a regression but an older bug which is only detected with that config change. Could you try again with CONFIG_INIT_STACK_ALL_ZERO=y instead? However, I don't see how this can be stack data. This error code is from qcom_rpm_smd_write() and I'm pretty sure it's from the ret = rpm->ack_status; assignment and it's supposed to be zero. regards, dan carpenter
