Commit 2dc0b46b5ea3 in v4.15-rc4 looks like it could be related. I built a Bionic test kernel with this commit reverted. The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1783906 Can you test this kernel and see if it resolves this bug? Thanks in advance! Note about installing test kernels: • If the test kernel is prior to 4.15(Bionic) you need to install the linux-image and linux-image-extra .deb packages. • If the test kernel is 4.15(Bionic) or newer, you need to install the linux-modules, linux-modules-extra and linux-image-unsigned .deb packages. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
