Bug 501054 – kernel 3.10.25 with ath9k - NULL pointer dereference in relay_open_buf.part.8

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description John Doe 2014-02-12 09:56:31 UTC]

When I have ath9k driver built-in kernel, I can't reboot or shutdown as it stops at 
kvm: exiting hardware virtualization
and I have to poweroff manually

Also, when I boot, there is mentioned a bug before logging in:

Thank you for filing this bug. Does this still happen on more recent kernels?

> kvm: exiting hardware virtualization

As a side note, this usually has to do with something else than what you brought forward in this bug; a quick internet search reveals that this is often the result of one or another particular device mount point that is still mounted.

Start your kernel with these additional parameters:

    debug ignore_loglevel log_buf_len=10M

Maybe you can get more details that way instead of just that kvm message.
