I downloaded the three files you mentioned and tried to install them using 'dpkg -i *.deb' as root. Two of the pkgs installed OK but the kernel proper did not, giving error:
Selecting previously unselected package linux-image-unsigned-4.15.0-22-generic. dpkg: regarding linux-image-unsigned-4.15.0-22-generic_4.15.0-22.25_lp1773704_amd64.deb containing linux-image-unsigned-4.15.0-22-generic: linux-image-unsigned-4.15.0-22-generic conflicts with linux-image-4.15.0-22-generic linux-image-4.15.0-22-generic (version 4.15.0-22.24) is present and installed. dpkg: error processing archive linux-image-unsigned-4.15.0-22-generic_4.15.0-22.25_lp1773704_amd64.deb (--install): conflicting packages - not installing linux-image-unsigned-4.15.0-22-generic I rebooted the system and as one might expect, the errors in dmesg log persist. I read up a bit on dpkg hoping I could -f "force" the installation but it appears more complicated than that. How to proceed? Strange, I've installed test kernels (for this same issue in fact, see bug ID #1710548, which did in fact fix the problem: but the typo in the re-write of the fix that found it's way into the distro uproots the fix). Again I have to underscore the fact that I've built my own kernels with line 184 changed to be identical to line 187 and the problems are solved. If that was your approach, please consider your fix to have been successfully tested. I didn't have much trouble installing the kernels I built so the above errors from dpkg are a mystery to me. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1773704 Title: Typo at line 184 in xhci-pci.c makes trouble for Renesas USB chipset in Bionic 18.04 Status in linux package in Ubuntu: In Progress Status in linux source package in Bionic: In Progress Bug description: A typo at line 184 in /drivers/usb/host/xhci-pci.c trashes a good fix. 183 if (pdev->vendor == PCI_VENDOR_ID_RENESAS && 184 pdev->device == 0x0014) 185 xhci->quirks |= XHCI_TRUST_TX_LENGTH; 186 if (pdev->vendor == PCI_VENDOR_ID_RENESAS && 187 pdev->device == 0x0015) 188 xhci->quirks |= XHCI_RESET_ON_RESUME; Line 184 should be identical to line 187, ie: should read pdev->device == 0x0015) I've compiled the kernel both with and without the typo.
