(llzen44@xxxxxxxxx) changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |llzen44@xxxxxxxxx --- Comment #31 from Loic S. (llzen44@xxxxxxxxx) --- Hi I had the same issue. HP Smart Array P400 controller in a HP DL385 migrating from Ubuntu 16.04 to 18.04, so a kernel going from 4.10.xx to 4.15.yy and kernel couldn't find the disk controller. I tried all the hpsa_xx, cciss_xx and rootdelay combinations in the boot parameters with no results. I ended up upgrading the P400 firmware (4.08 to 7.24) and it worked straight without any parameter change. Server and disk access is still ok after a few days of testing. Thanks for the tip.
