Happens for both TX and RX on Ubuntu 24.04.2 with kernel 6.11.0-21-generic and mainline kernel build 6.14.2-061402-generic. It appears to be related to hangs at reboots and poweroffs.
The TX and RX warning happens, - On suspension (s2idle) - On reboot/poweroff - After boot (if nvidia driver blacklisted) Tests: blacklist nvidia => happens after boot, reboot hangs blacklist nvidia + immediate reboot => does not hang not blacklist + reboot => does not hang not blacklist + suspend => happens after suspend, reboot hangs blacklist thunderbolt => does not hang regardless of suspension Abnormal reboot behaviour is, 1. Same TX and RX warnings again 2. NX-protected page execution OR kernel NULL dereference 3. recursive fault (scheduling while atomic) 4. hanging there with cursor blinking; not responding to SysRq and no WDT warning but not panicking either. Kernel logs from netconsole are attached below. Tails of logs are truncated depending on the timing r8168 gets unloaded, but on screen it always ends with the same recursive fault as shutdown-dmesg.txt. ** Attachment added: "shutdown-dmesg.txt" https://bugs.launchpad.net/ubuntu/+source/linux-signed/+bug/2052411/+attachment/5871067/+files/shutdown-dmesg.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2052411 Title: thunderbolt: interrupt for TX ring 0 is already enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed/+bug/2052411/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
