[Bug 1220821] [NEW] Kernel Panic playing Youtube

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Hi, there.

Was playing the video at the footer of http://www.instructables.com/id
/Arduino-controlled-RGB-LED-Infinity-Mirror/?ALLSTEPS within the latest
version of Google Chrome (at the time of writing) and it caused a Kernel
Panic (CPU maxed to 100%, fans running hot, unresponsive mouse pointer,
keyboard, a cycling sound sample from the video and CTRL+ALT+F1 was
unresponsive).

After rebooting, Apport offered to file a bug, which then told me it had
already been reported, and only to comment if I could add extra
information to the bug. It promptly redirected me to a 404 on launchpad,
identifying no bug at all.

Just before the kernel panic, the machine seemed to become unresponsive,
kswapd0 was using an increasing amount of CPU (even though memory was
relatively free - about 60% RAM and 30% swap (whilst I could still
actually observe the stats, and before the slowdown and crash).

Can anyone identify what the bug actually was, since Apport refused to
file it for its own personal reasons? Since apport is broken, I can't
access the bug and establish if it is indeed the same bug, or see if
there are workarounds.

I'm now running the latest mainline kernel based off
linux-*-3.11.0-031100-generic_3.11.0-031100.201309021735_i386 (which is
saucy final if I understand the mainline directories correctly). I'll
update this bug if the issue recurs with the new mainline (though I was
getting regular, identical freezes with 3.11 saucy rc6 -  the previous
kernel I ran.
