This happens to me, lunar, kernel 2.6.0-20, Lenovo Carbon X1 gen 7, Dell monitor with built-in thunderbolt hub. Seems to happen more likely with big graphic updates (such as page change in Firefox).
(Monitor/hub works flawlessly with a dell laptop) It starts with [ 2713.078178] pcieport 0000:06:04.0: pciehp: Slot(4): Link Down [ 2713.078183] pcieport 0000:06:04.0: pciehp: Slot(4): Card not present and usually flaps up and down a few times before recovering. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed-hwe in Ubuntu. https://bugs.launchpad.net/bugs/1827042 Title: ThunderBolt "flaps" on laptop with 32G RAM Status in linux-signed-hwe package in Ubuntu: Confirmed Bug description: I'm running ubuntu 18.04 desktop on a new laptop and use an external thunderbolt 3 dock. Everything was running quite fine with stock kernel during about one week, while I was having 16G RAM in the laptop. Yesterday, I upgraded RAM to 32G. Now the thunderbolt link flaps (down/up, see attached dmesg) from time to time (could be twice in a few minutes or run for one hour without noticeable problem). The only change made to trigger this issue was upgrading RAM from 16 to 32G. Downgrading from 32 to 16G stops the issue from happening again (kernel 4.18.0 and 5.0.10). Stock kernel (4.18.0-18) or mainline 5.0.10 exhibits the same behaviour. extract from dmesg (32G RAM, 5.0.10 kernel, full file attached): [ 151.538361] pciehp 0000:02:01.0:pcie204: Slot(1): Link Down [ 151.538370] pciehp 0000:02:01.0:pcie204: Slot(1): Card not present [ 151.538400] pcieport 0000:05:04.0: Refused to change power state, currently in D3 [ 151.539915] pcieport 0000:05:03.0: Refused to change power state, currently in D3 [ 151.540508] xhci_hcd 0000:08:00.0: remove, state 1 [ 151.540530] usb usb8: USB disconnect, device number 1 [ 151.540537] usb 8-1: USB disconnect, device number 2 [ 151.540802] xhci_hcd 0000:08:00.0: xHCI host controller not responding, assume dead [ 151.550115] thunderbolt 0-1: device disconnected [ 151.607033] xhci_hcd 0000:08:00.0: USB bus 8 deregistered [ 151.607042] xhci_hcd 0000:08:00.0: remove, state 1 [ 151.607047] usb usb7: USB disconnect, device number 1 [ 151.607048] usb 7-3: USB disconnect, device number 2 [ 151.722465] pcieport 0000:05:01.0: Refused to change power state, currently in D3 [ 151.843046] xhci_hcd 0000:08:00.0: Host halt failed, -19 [ 151.843049] xhci_hcd 0000:08:00.0: Host not accessible, reset failed.
