I built a test kernel with debug output as requested by upstream. Can you test this kernel and post your syslog or dmesg output?
The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1783906 This kernel should exhibit the bug, but will write to syslog with output like: ***-> Value of spd_limit: N ***-> Value of sstatus: N ***-> Value of spd: N ***-> Value of mask: N I did a dump_stack in the function, so you should see a new stack trace as well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1783906 Title: Linux 4.15 and onwards fails to initialize some hard drives To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1783906/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
