[Kernel-packages] [Bug 1338706] Re: Samsung SSD 840 failed to get NCQ Send/Recv Log Emask 0x1 failed to set xfermode (err_mask=0x40) on upstream kernels = 3.12

Seems this one has been commited after the -20 build :(

Title:
Samsung SSD 840 failed to get NCQ Send/Recv Log Emask 0x1 failed to
set xfermode (err_mask=0x40) on upstream kernels = 3.12

Bug description:
[Impact]
* Users with Samsung 8** SSD drives see miscellaneous errors and
warning messages in the logs depending on the firmware level of the
drive while booting or after running trim.
[Test Case]
* Run this script, and then check logs for errors.
#!/bin/bash
git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
for i in {0..10} ; do
cp -r linux linux$i
done
rm -rf linux*
echo sudo fstrim requires your password
sudo fstrim ./
[Regression Potential]
* There is very little regression potential as this change simply
prevents NCQ trim from being used on Samsung 8** drives.
[Other Info]
* Commit is upstream.
* Greatly increasing the timeout for the drives seems to relieve the timeout
errors. This may be due to trimming large numbers of sectors with single
commands. It may be prudent for future upstream to break up large trims into
multiple requests on smaller regions.

[Kernel-packages] [Bug 1401817] [NEW] memory leak with unknown reason after upgrade to utopic
Public bug reported: I'm not sure if this is the right component/package. We are not able to identify a package/program which could be responsible for this bug, so we assume it is the kernel or at least a kernel configuration. Since the upgrade from trusty to utopic at October 27., our three servers for package building are massively swapping. This leads to by a factor of four slower build times. There were no configuration changes at all. Munin graphs of one of the affected servers are attached.

We are not able to identify a package/program which could be responsible for this bug, so we assume it is the kernel or at least a kernel configuration. Since the upgrade from trusty to utopic at October 27., our three servers for package building are massively swapping. This leads to by a factor of four slower build times. There were no configuration changes at all. Munin graphs of one of the affected servers are attached. The system has 48GB memory, and we have configured several ramdisks: root@cx1000-02:~# mount | grep -E tmpfs|ramfs none on /sys/fs/cgroup type tmpfs (rw,uid=0,gid=0,mode=0755,size=1024) udev on /dev type devtmpfs (rw,mode=0755) tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755) none on /run/lock type tmpfs (rw,nodev,noexec,nosuid,size=5242880) none on /run/shm type tmpfs (rw,nosuid,nodev) none on /run/user type tmpfs (rw,nodev,noexec,nosuid,size=104857600,mode=0755) tmpfs on /var/tmp/obs type tmpfs (rw,size=36G) tmpfs on /run/obs type tmpfs (rw,relatime,size=1G) ramfs on /var/obscache type ramfs (rw) tmpfs on /run/obs type tmpfs (rw,relatime,size=1048576k) The build service uses several chroot environments to build packages for several distributions (http://openbuildservice.org/). You don't see any process which allocates so much memory with 'top'. Even after stopping the build service and unmounting /var/tmp/obs you are not able to deactivate the swap via swapoff -a: root@cx1000-02:~# swapoff -a swapoff: /dev/sda5: swapoff failed: Cannot allocate memory We also tested the latest kernel (3.16.0-28) and an old trusty kernel (3.13.0-40) without success. Also patching perl to exclude the perl bug https://rt.perl.org/Public/Bug/Display.html?id=123198 as root cause doesn't help. We don't have any idea what's the cause for this problem... We can deploy debug packages or anything else on the system, so please hesitate to ask for any information or help.
