Greg Kroah-Hartman announced the release of Linux Kernel 3.19.1 yesterday and urged all users of Kernel 3.19 series to upgrade as soon as possible.
According to the release note, Linux Kernel 3.19.1 brings improvements to ARM, x86, PowerPC, MIPS, ARM64, and s390 architectures, updated drivers for wireless, USB, ACPI, Bluetooth (ath3k), CPUFreq, HID, MD/RAID, MMC, DVB, PCI, SCSI, TTY, and XEN. Additionally, the XFS, UDF, NFS, JFFS2, OCFS2, EXT4, and Btrfs filesystems received various enhancements.

If you need a low latency system (e.g. for recording audio) then replace the second and third packages with:
For Ubuntu Server without an UI, you may run below commands one by one to download & install the kernel debs.
For 64-bit system, run:

Tip: For Desktop machine running with a proprietary video driver, you may have to re-build/re-install the driver for the new kernel.
If for some reason, the new kernel does not work properly for you, reboot with the previous Kernel (Grub boot loader -> Advanced -> select previous kernel) and run below command to remove the Linux Kernel 3.19.1:
sudo apt-get remove linux-headers-3.19.1-* linux-image-3.19.1-* && sudo update-grub
Thanks for this prompt update. Using btrfs for /home so I think it is best to use the latest and greatest kernel. 3.19.1 now up and running on my Ubuntu 14.04 Server AMD64…
3.19.1 plays real nice with amd/radeon cards booted up flawlessly and much snappier thann with the 3.19 generic base on 15.04 kubuntu
I just used this with a custom Ubuntu install I have. The official vivid repo only has 3.19.0 still for some reason and when I install it then my USB and Wireless completely stops working.
The method here of getting it from the link above is much more helpful. It is on 3.19.2 and on installing it my USB and Wireless are working fine so far. So I will probably also give it a try on my desktop as well again since it appears to be working on my laptop just fine.
