[Test Case] Apply to kernel and boot with the nvme module installed. Now the device should be probed with success. ``` kernel: [ 1.731760] nvme nvme0: pci function 10000:e1:00.0 kernel: [ 1.731778] pcieport 10000:e0:06.0: can't derive routing for PCI INT A kernel: [ 1.731780] nvme 10000:e1:00.0: PCI INT A: no GSI kernel: [ 1.731919] nvme nvme0: bad crto:0 cap:800203028033fff kernel: [ 1.735550] nvme nvme0: Shutdown timeout set to 10 seconds kernel: [ 1.753865] nvme nvme0: allocated 64 MiB host memory buffer. kernel: [ 1.794966] nvme nvme0: 16/0/0 default/read/poll queues kernel: [ 2.136735] nvme0n1: p1 p2 p3 ``` [Where problems could occur] This patch tries to set an appropriate CRTO (Controller Ready Timeouts) that may be reported incorrectly by some devices. There should be little (a bit longer CRTO) to no effect on devices performing normally before hands. [Other Info] While this has been in Linus' tree, Mantic/Lunar/oem-6.5 and oem-6.1 will be nominated. ========== original bug report ========== NVME module left unready, therefore not recognized by the installation process, and/or after installation with following error messages: kernel: [ 1.754585] nvme nvme0: pci function 10000:e1:00.0 kernel: [ 1.754595] pcieport 10000:e0:06.0: can't derive routing for PCI INT A kernel: [ 1.754599] nvme 10000:e1:00.0: PCI INT A: no GSI kernel: [ 1.756743] nvme nvme0: Device not ready; aborting initialisation, CSTS=0x0 To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/2041495/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
