[Bug 1375637] Re: Premature end of data in tag file line 247651 with libxml2
FWIW, I am currently experiencing the same error when running "createrepo" on a repo containing 20 RPMs. The host system is running Ubuntu 14.04.5 LTS, libxml2 version is 2.9.1+dfsg1-3ubuntu.

[Bug 1415859] Re: Immediate I/O errors when dd-ing data to an external USB3 disk
As I wrote in the initial report: "This seems to be a regression in the mainline Kernel, as the default kernel (3.13.0-44-generic) performed this dd operation without issues - but it seems to be using a different USB driver for the disk" I also included the relevant kernel output. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1415859 Title: Immediate I/O errors when dd-ing data to an external USB3 disk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1415859/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1415510] Re: Frequent kernel panics when doing heavy I/O in LXC containers on Btrfs
Update: using the mainline kernel, I observe a slightly different pattern. When running multiple heavy I/O operations in parallel (e.g. rsyncing a large ISO image to a container, performing an http upload into another one and running "yum update" on all containers), the large uploads start to stall and come to a crawling halt at some point.

[Bug 1415510] Re: Frequent kernel panics when doing heavy I/O in LXC containers on Btrfs
Hi Joseph, thanks for your quick reply. The problems began some time after I started using LXC with Btrfs on Trusty, but I'm not sure if a particular kernel update introduced a regression. I've been using Btrfs on my home directory previously as well, but did not experience similar I/O-related crashes. I'll try using the latest upstream kernel and report back. The problem is that these crashes happen randomly, I have not yet been able to reproduce them reliably (and since this always brings down my entire work environment, I'm not too excited about these crashes, as you can probably imagine). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1415510 Title: Frequent kernel panics when doing heavy I/O in LXC containers on Btrfs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1415510/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1415510] [NEW] Frequent kernel panics when doing heavy I/O in LXC containers on Btrfs
Public bug reported:
I initially reported this as a bug in LXC
(https://github.com/lxc/lxc/issues/424), but I was (rightfully) advised
to report this as a kernel issue instead:
I'm running Ubuntu 14.04.1 LTS (x86_64) on my Laptop. Current Kernel
version is "3.13.0-44-generic". The LXC version is "1.0.7-0ubuntu0.1",
installed from the "ubuntu-lxc" PPA on Launchpad.
I have a dedicated Btrfs file system mounted on /container/, which I use
for storing all LXC containers.
The file system is created on top of a logical volume:
lenz@lenz-ThinkPad-T440 ~ % mount | grep container
/dev/mapper/ubuntu--vg-container on /container type btrfs (rw)
lenz@lenz-ThinkPad-T440 ~ % sudo lvdisplay /dev/mapper/ubuntu--vg-container

- currently set to 256
Block device 252:5
The hard disk drive is a Samsung SSD ("Samsung SSD 840 EVO 500GB,
EXT0BB0Q, max UDMA/133", according to dmesg).
I have a number containers based on CentOS 6, these were created by
cloning a base image using lxc-clone -s.
Quite frequently, when I create heavy disk I/O in one or several of
these containers (e.g. by running yum update concurrently, or by
transferring large files e.g. via a HTTP upload to one of the container
instances), my host system freezes. This only happens when container
activity is involved, the system runs stable otherwise. Most of the time
the X desktop freezes, sometimes a Kernel panic can be observed on the
console. Unfortunately I'm unable to capture it other than by taking a
picture. The only solution is to perform a cold reboot using the power
button.
This occurred to me before. I then re-created the /container/ file
system from scratch and started again. But now it's happening again, so
I would like to report it for investigation.
