Carefully comparing them found BYTE 6 is changed from 0x18 to 0x10, i.e. BIT3 changed. According to PCI spec, it is Status Register and its "interrupt Status" (This read-only bit reflects the state of the interrupt in the device/function.) This can indicate the device was be used when fwts reads its pci registers. This can also be safely ignored. ** Changed in: linux-lts-saucy (Ubuntu) Status: New => Opinion ** Changed in: linux-lts-saucy (Ubuntu) Importance: Medium => Low -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1284926 Title: [Lenovo B490s] fwts: FAILED [HIGH] DevConfigDiffAfterS3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-saucy/+bug/1284926/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
