I presume that Dell doesn't use the hpsa driver, but both are hanging at approximately the same time in the boot up process and the same subsystems appear to be involved... I would speculate that they have something in common that is triggering this. -- 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/1765105 Title: HP Smart Array driver fails to load, kernel panics boot process Status in linux package in Ubuntu: Confirmed Bug description: Hi I have an HP ProLiant G6 with a Smart Array controller on Bionic, Kernel 4.15.0-15, that fails to load the hpsa driver for the Smart Array, (occasionally) drops to the initramfs shell, as it cannot find a root device in a reasonable amount of time, and then finally kernel panics with the stack trace leading to the hpsa driver. Occasionally it will complain about resetting the logical volume scsi bus. Downgrading to the previous kernel 4.15.0-13 works just fine. Attached is a screenshot showing the kernel panic, and below is a link to a YouTube video of the whole boot process, a video recording from ILO. To save you the time of watching the whole thing, 39 seconds is the bus reset error, then it hangs around waiting for a root device, and the kernel panics at 4:16.
