For my fellow Linux neophytes, here are some great links and a summary of what is different in the new Linux kernel 2.6.24.3, included in unRAID 4.3.

2.6.24 includes CPU "group scheduling", memory fragmentation avoidance, tickless support for x86-64/ppc and other architectures, many new wireless drivers and a new wireless configuration interface, SPI/SDIO MMC support, USB authorization, per-device dirty memory thresholds, support for PID and network namespaces, support for static probe markers, read-only bind mounts, SELinux performance improvements, SATA link power management and port multiplier support, Large Receive Offload in network devices, memory hot-remove support, a new framework for controlling the idle processor power management, CIFS ACLs support, many new drivers and many other features and fixes.

 

And here's the page it came from, http://kernelnewbies.org/Linux_2_6_24, a fascinating piece of work summarizing the changes.  Unbelievable how much work has gone into this, and how much progress has been made.  Although long, it is actually interesting to skim through, as I think it very likely you will find some mention of an improvement for at least one piece of your hardware.  I noticed that NCQ support had been added to the sata_nv driver, which my board uses.

 

Another great web site is the Linux Weather Forecast http://www.linux-foundation.org/en/Linux_Weather_Forecast.  After linking to the KernelNewbies 2.6.24 page, it has this paragraph:

Some statistics: over 10,000 individual changesets were merged into the mainline during the 2.6.24 development cycle. These came from some 950 developers representing over 130 companies. Almost 300,000 lines of code were added during this cycle, and many more modified. It is an amazing amount of work, even by kernel standards.

 

And 2.6.25 is going to be released any time now!

Thanks for posting this.  Good stuff!

And 2.6.25 is going to be released any time now!

 

And now it has been!  It does not appear to have that much changed in it though, from an unRAID user's perspective.  Perhaps memory management enhancements and ACPI thermal regulation support may be useful to us.  Each version does add stability improvements and additional hardware supported.
