Seems like everything gets locked, including the kernel. I tried connecting through SSH but it isn't answering.
debug1: Connecting to ariel-nt [ariel-nt] port 22. debug1: connect to address ariel-nt port 22: No route to host ssh: connect to host ariel-nt port 22: No route to host I also tried pinging it, when it freezes it also stops answering. # Before booting >From _ icmp_seq=30 Destination Host Unreachable >From _ icmp_seq=31 Destination Host Unreachable >From _ icmp_seq=32 Destination Host Unreachable >From _ icmp_seq=33 Destination Host Unreachable >From _ icmp_seq=34 Destination Host Unreachable >From _ icmp_seq=35 Destination Host Unreachable >From _ icmp_seq=36 Destination Host Unreachable >From _ icmp_seq=37 Destination Host Unreachable >From _ icmp_seq=38 Destination Host Unreachable >From _ icmp_seq=39 Destination Host Unreachable # Connected to the internet 64 bytes from ariel-nt: icmp_seq=40 ttl=64 time=2512 ms 64 bytes from ariel-nt: icmp_seq=41 ttl=64 time=1490 ms 64 bytes from ariel-nt: icmp_seq=42 ttl=64 time=467 ms 64 bytes from ariel-nt: icmp_seq=43 ttl=64 time=33.6 ms 64 bytes from ariel-nt: icmp_seq=44 ttl=64 time=39.4 ms 64 bytes from ariel-nt: icmp_seq=45 ttl=64 time=6.22 ms 64 bytes from ariel-nt: icmp_seq=46 ttl=64 time=7.62 ms 64 bytes from ariel-nt: icmp_seq=47 ttl=64 time=6.84 ms 64 bytes from ariel-nt: icmp_seq=48 ttl=64 time=3.22 ms # Froze >From _ icmp_seq=97 Destination Host Unreachable >From _ icmp_seq=98 Destination Host Unreachable >From _ icmp_seq=99 Destination Host Unreachable >From _ icmp_seq=100 Destination Host Unreachable >From _ icmp_seq=101 Destination Host Unreachable >From _ icmp_seq=102 Destination Host Unreachable >From _ icmp_seq=103 Destination Host Unreachable >From _ icmp_seq=107 Destination Host Unreachable >From _ icmp_seq=108 Destination Host Unreachable -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1917194 Title: [Dell G5 5590] lspci freezes computer on Ubuntu 20.04 Status in linux package in Ubuntu: Confirmed 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.
