Product: HP ZBook G3 17
Operating System: Linux

Hello,

 

I recently bought laptop HP ZBook G3 17 which has 500GB hard drive. I also both M.2 250GB SSD Samsung drive and install according to the manual. Then I install an Arch Linux operating system, everything was working as expected. Since ZBook G3 has also 1 free slot for a SATA drive I decided to also install a drive from my old laptop. To summarize, I now have 2 SATA HDD drives (one 500GB and one 640GB) and one M.2 SDD (250GB). All disks are working fine but I discovered that some other devices (for example integrated Intel graphics card) are not recognized by the system (they are missing from lspci command output). When I disable the second SATA bus in BIOS everything is again normal and system recognize all devices as expected.

 

What can cause this kind of behavior? Is there a limit on number of drives motherboard bus can handle? I also tried another Linux distribution (with different kernel version) with the same result.
