Hi Adrian, thanks for the pointers. I ran the following (I already set grub to default to 4.15.0-20 unlessI select an alternate);
git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git -b linux-5.4.y cd linux/ wget https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1848883/+attachment/5311741/+files/0001-mmc-sdhci-pci-Fix-premature-clock-gating-of-CQHCI-on.patch git am 0001-mmc-sdhci-pci-Fix-premature-clock-gating-of-CQHCI-on.patch make localmodconfig make -j`nproc` deb-pkg dpkg -i *.deb reboot After booting to 5.4.3+ I see the same cqhci/sdhci register dump errors (these look the same as https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1848883/comments/14 ). I also noticed just before the register dumps some TPM errors but realised I still had TPM enabled in the bios so I've disabled this. Only way I can think of to get these messages is build out 18.04 on a usb drive. Then build the same patched kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848883 Title: (Lenovo S130-11IGM) emmc not working in 19.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1848883/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
