[Kernel-packages] [Bug 381059] Re: use zram-config by default
The Ubuntu kernels also have zswap since Saucy. It may be a simpler option, needing only a change to the kernel command-line ( add "zswap.enabled=1" ). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/381059 Title: use zram-config by default Status in “linux” package in Ubuntu: Confirmed Status in “ubiquity” package in Ubuntu: Confirmed Status in “zram-config” package in Ubuntu: Invalid Status in “linux” source package in Raring: Confirmed Status in “ubiquity” source package in Raring: Confirmed Status in “zram-config” source package in Raring: Invalid Bug description: There is already zram-config in Ubuntu, a package to enable compressed RAM swap: https://launchpad.net/ubuntu/+source/zram-config Starting with kernel 3.8 zram (a rewrite of older compcache) is out of staging. Please enable it by default. See also: http://www.webupd8.org//2011/10/increased-performance-in-linux-with.html https://launchpad.net/~shnatsel/+archive/zram === Original description === Including compcache by default can have a number of benefits for the average, and not so average, Ubuntu user. For the average user, compcache will decrease disk swapping, which will increase perceived performance and decrease hits, which for laptop users will improve battery life. Since many users use laptops and netbooks these days, this is a big audience and would make many people happy. Desktop users will also benefit, as their disks will be less active and their electric bills may go down a tiny bit. For the not-so-average user, such as those that run virtualization, they can run more VMs. With Ubuntu striving to be bigger in the server space, this could be a big deal. For me, I (unfortunately) run Windows in KVM, and it appears that enabling compcache improves my VM's performance. Embedded devices and netbooks (such as those that run Ubuntu Netbook Remix) will benefit, as they have little RAM, and since compcache sort of increases RAM, it will make these devices more capable. Since compcache is already in the Ubuntu kernel (see bug 200765), the only thing left is to either add an initramfs script or a udev script (IMHO, the udev approach is cleaner) as described here: https://wiki.ubuntu.com/Compcache compcache: http://code.google.com/p/compcache/ Thanks!

[Kernel-packages] [Bug 1173423] Re: Kernel fails to update EFI vars, rendering system unbootable [P8P67 PRO REV 3.1, BIOS 1904 08/15/2011]
Hi, I seem to have hit this same bug with linux-image-generic-lts-raring
3.8.0-30.44~precise1 in Precise.
Was this fix applied in the 3.8 kernel in the Raring stack in 12.04.3LTS ?

Title:
Kernel fails to update EFI vars, rendering system unbootable [P8P67
PRO REV 3.1, BIOS 1904 08/15/2011]
Status in The Linux Kernel:
Confirmed
Status in “linux” package in Ubuntu:
Fix Released
Status in “linux” source package in Raring:
Fix Committed
Status in “linux” source package in Saucy:
Fix Released
Bug description:
After an upgrade, my system failed to boot. Fortunately I was able to
run the EFI shell and manually launch grub. From there I discovered
that the EFI boot catalog contained no entry for GRUB. It appears
there has been a regression in kernels later than 3.8.0-7 that causes
it to fail to update the EFI variables. After running grub-install,
it reports no errors, yet fails to show the efi boot catalog as it
does when it works. Manually running efivars shows the ubuntu entry
has been removed. Checking dmesg shows:
[ 25.965586] efivars: set_variable() failed: status=8009
[ 25.981816] efivars: set_variable() failed: status=8009
This happens on kernels 3.8.0-{15,19,23} but works correctly in -{6,7}.
