Carefully comparing them found BYTE 7 is changed from 0x08, 0x40 to 0x00, it is Status Register(These read-only bits reflect the temporary status of the device/function when fwst read the register). These bits are "Signaled Target Abort", "Signaled System Error". This can indicate that before sleeping, it happened a target device terminates a transaction with Target-Abort, and device asserts SERR# error signal, but after wake these error status disappeared.
I think this can be safely ignored. ** Changed in: linux-lts-saucy (Ubuntu) Status: New => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1308480 Title: [HP Pavilion 20 AIO] High failures (DevConfigDiffAfterS3) found in suspend / hibernate report To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-saucy/+bug/1308480/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
