Linux Kernel 3.19.3

The third release of Linux Kernel 3.19 series was released yesterday by Greg Kroah-Hartman. All users of this kernel series were urged to upgrade as soon as possible.

Linux Kernel 3.19.3 comes with many fixes and enhancements for ARM, ARM64, PowerPC, s390, SPARC, and x86 architectures, fixes to the FUSE and NILFS2 file systems, updated drivers for Radeon and Intel graphics cards, sound and networking improvements. See the changelog for details.

How to Upgrade to Kernel 3.19.3:

For Desktop users, first check out your OS type, 32-bit (i386) or 64-bit (amd64), then download and install the packages below in turn:

  • linux-headers-3.19.3_xxx_all.deb
  • linux-headers-3.19.3-xxx-generic_3.19.3-xxx_i386/amd64.deb
  • linux-image-3.19.3-xxx-generic_3.19.3-.xxx_i386/amd64.deb

from the kernel.ubuntu.com.

After installing the kernel, you may run sudo update-grub command in terminal (Ctrl+Alt+T) to refresh grub boot-loader.

If you need a low latency system (e.g. for recording audio) then download & install below packages instead:

  • linux-headers-3.19.3_xxx_all.deb
  • linux-headers-3.19.3-xxx-lowlatency_3.19.3-xxx_i386/amd64.deb
  • linux-image-3.19.3-lowlatency_3.19.3-xxx_i386/amd64.deb

Linux Kernel 3.19.1

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. Several core components have also been updated, and some Ceph, IPv4, and SunRPC issues have been fixed.

Linux Kernel 3.19

The first stable release of Linux Kernel 3.19 was released yesterday by Linus Torvalds. He wrote on the Linux Kernel Mailing List:

So nothing all that exciting happened, and while I was tempted a couple of times to do an rc8, there really wasn’t any reason for it.

Just as an example, Sasha Levin used KASan and found an interesting bug in paravirtualized spinlocks, but realistically it’s been around forever, and it’s not even clear that it can really ever trigger in practice. We’ll get it fixed, and mark it for stable, and tempting as it was, it wasn’t really a reason to delay 3.19.

And the actual fixes that went in (see appended shortlog) were all fairly small, with the exception of some medium-sized infiniband changes that were all reverting code that just wasn’t ready.

So it’s out there – go and get it. And as a result, the merge window for 3.20 is obviously also now open.

What’s new in the Linux Kernel 3.19:

  • SI/CI SMC fan control support within the Radeon driver. Should reduce the fan noise on systems with a higher default fan profile.
  • Initial GM204 GPU support (NVIDIA GeForce 900 series) in Nouveau driver
  • RAID 5 and RAID 6 level support is better off in the Btrfs file-system
  • LZ4 Compression Support for SquashFS
  • multi-touch for more Logitech devices
  • New keyboard backlight support in DELL laptop. ThinkPad ACPI driver reworked to simplify sound muting. Toshiba ACPI driver improvements
  • The initial hardware enablement for Skylake, Intel’s successor to Broadwell
  • AMD HSA open-source support is closer to reality
  • and more ….
