It could be a problem with how the kernel was configured. It could be a hardware issue; it could be many things. But the problem seems to be that the root device is not getting detected, so this is before the file system gets involved. Part of the problem is that hardware support issues are one of the things that take a quite a lot of time to try to resolve remotely, especially if the user doesn't know how to get the necessary debugging information, and upstream developers are all volunteers when it comes to giving support to random end users. Normally this is work that gets done by distributions, especially if they are getting paid support $$$. But they don't want to support anything other than their standard kernel. You can find kernel folks who also have a particular hardware, or something similar, and they will help on a volunteer basis. The problem is while many of us will have Thinkpads (for example), many fewer kernel developers are likely to have come across an All-in-one Lenovo A740 desktop. This sort of problem is much better handled by someone who knows how to get the necessary debugging information (the kernel configuration used to build the kernel image you are trying to use, and the kernel dmesg messages during the boot process, etc.). So if you are near a local Linux User's Group, that might be a good place to try to ask for help. I will say that my Haswell-based Lenovo Thinkpad T540p works just fine with upstream kernels, so my guess is that it's mostly a kernel configuration issue, possibly combined with needing to make changes in the BIOS settings. So there's a good chance this isn't a kernel bug at all. -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
