I have also experienced a similar issue with my new Thinkpad P1 Gen6. Since I am dependent on the new Thunderbolt ports for my videography work, the laptop is essentially useless now. Lenovo replaced the motherboard yesterday and there was no change in the behaviour. On doing some research, I see that similar issues have occurred for a long time. In any case, the key lines in my dmesg, leading to failure are:
[ 125.804774] pcieport 0000:00:1d.0: AER: Uncorrectable (Fatal) error message received from 0000:20:00.0 [ 125.804793] pcieport 0000:20:00.0: AER: PCIe Bus Error: severity=Uncorrectable (Fatal), type=Inaccessible, (Unregistered Agent ID) [ 125.804803] thunderbolt 0000:22:00.0: AER: can't recover (no error_detected callback) [ 125.804807] xhci_hcd 0000:48:00.0: AER: can't recover (no error_detected callback) [ 125.937470] pcieport 0000:00:1d.0: AER: Root Port link has been reset (0) [ 125.937563] pcieport 0000:00:1d.0: AER: device recovery failed .... Then the system simply gives up as follows: [ 149.485418] xhci_hcd 0000:48:00.0: xHCI host controller not responding, assume dead [ 149.485440] xhci_hcd 0000:48:00.0: HC died; cleaning up Incidently, I created a bootable Windows disk today and confirmed that this issue is only related to Linux. I have also tried updated kernels, 6.8.8 and now 6.8.10 and the issue is still present. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1990272 Title: PCIe Bus Error: Uncorrected, Transaction Layer, device [8086:51b0],AER UnsupReq To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1990272/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
