After upgrading to 19.04 disco, the system is still too unstable to be useful. The current kernel is 5.0.0-13-lowlatency (buildd@lcy01-amd64-020).
I note the Intel driver has not changed after the upgrade from 18.10 cosmic, i.e. still iwlwifi-7265D-29.ucode, packaged within linux- firmware version 1.178. The details of the stack trace are different, but the outcome is the same (attached). The wifi connection is lost and kernel error messages spew out to the log. Stopping and restarting wifi makes no difference. The only "solution" is to shut down the system and reboot. Luckily I have a usb dongle that uses rtlwifi firmware, which works OK. ** Attachment added: "disco kernel log when intel driver hang is reported" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1776443/+attachment/5261968/+files/bacchus-iwlwifi-hang-log-disco-2019-04-27 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1776443 Title: iwlwifi-29 kernel timeout queue active on fifo 2 and stuck To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1776443/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
