Linux 3.19 Kernel To Start 2015 With Many New Features
An anonymous reader writes Linux 3.18 was recently released, thus making Linux 3.19 the version under development as the year comes to a close. Linux 3.19 as the first big kernel update of 2015 is bringing in the new year with many new features: among them are AMDKFD HSA kernel driver, Intel "Skylake" graphics support, Radeon and NVIDIA driver improvements, RAID5/6 improvements for Btrfs, LZ4 compression for SquashFS, better multi-touch support, new input drivers, x86 laptop improvements, etc.
The kernel and friends manage hotplug devices quite nicely.
I take that to mean you want a clickity-click GUI, so you can see what the system has already detected and handled properly for you, and do things without needing to understand what you're doing. If that's what you're looking for, hardinfo is a well-known option. Your choice of graphical desktop environment probably has one it provides by default as well. Look under "System" or similar.
As far as I know, they found the cause (it seems the kernel doesn't handle well some clock issues and clock overflow), and Linus send a RFC-like patch that kinda "fixes" the thing but it is so hackish that it needs to be discussed, generalized and ironed out. DaveJ doesn't have access to the hardware triggering the issue anymore, so it may be a while before they can actually fix it in a proper manner.
On the way to figuring out the cause for that bug, they found other lockup issues with similar symptoms but completely different causes and fixed them.
