Title:
[Dell G5 5590] lspci freezes computer on Ubuntu 20.04
Status in linux package in Ubuntu:
Incomplete
Bug description:
After upgrading from Ubuntu 18.04 to 20.04 my computer started to
freeze when running lspci.
I ended up noticing that it happened when trying to query device
'1f:00.0' a USB port. After some kernel and bios updates the problem
got worse. Now the computer freezes ~5 seconds after booting up.
I tried:
1) Running in recovery mode, also freezes
2) Running an older kernel version (5.4.0-66-generic), also freezes
3) Removing nvidia drivers (just in case), also freezes
4) Running all combinations nodemodeset, acpi=off an nouveau blacklisting
5) Updating all drivers
The computer freezes for ever, I can't switch TTYs, move the mouse,
anything, the only way to leave was to force shutdown. On the last
cases after switching to a tty I could see this messages before the
freeze ocurred:
kernel: xhci_hcd 0000:1f:00.0: PCI post-resume error -19!
kernel: xhci_hcd 0000:1f:00.0: HC died; cleaning up
Running Ubuntu 20.04 from a USB sticks works fine, as well as doing a fresh
install.
All logs were obtained by chrooting to the faulty partition from a fresh
install, if there are any more logs that would be helpful, let me know.
