Is your mSD a Samsung A2 one? Seems that these cards are a source of problems:
https://forums.raspberrypi.com/viewtopic.php?t=381997&hilit=microsd+a2&start=25#p2286123 There is a dtparam to manage the Command Queueing of mSD cards: From /boot/firmware/overlays/README sd_cqe Set to "off" to disable Command Queueing if you have an incompatible Class A2 SD card (Pi 5 only, default "on") Source here: https://forums.raspberrypi.com/viewtopic.php?t=367459&start=125#p2284988 So you may replace that quirk by inserting dtparam=sd_cqe=off in /boot/firmware/config.txt and test if it solved the problem. The case is that I don't know if current Ubuntu kernel is ready for that dtparam. BTW: as far as I know the kernel is going to be be changed to only activate cfq for known mSD A2 cards using a whitelist. So in a future the dtparam=sd_cqe=off should be unnecessary as it will be the default (will be used for the opposite option): https://github.com/raspberrypi/linux/pull/6591 and https://github.com/raspberrypi/linux/issues/6561 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2096773 Title: mmc0: running CQE recovery with linux-image-6.11.0-1006-raspi on Raspberry Pi 5B/16GB (revision e04171) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/2096773/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
