The first bug seems to fit the description, but I don't see the errors in the log. Next time it happens I'll check the logs right away.

Thank you. That is a good point. I do have LVM storage on a few of my VM's that do heavier IO.

So at this point, I will see if the problem recurs and try to track down more information. I will also run memtest on my system later tonight.

The Errors that I'm finding so far in my logs are these (Note this is just a few of each error, edited down )

I am interested in bug fixes to the ALSA driver that were added to the v3.9 kernel. I don't find a 3.9 kernel in the ubuntu mainline kernel directory for 12.04 (precise). This article,...

I have an older Sierra Wireless USConnect Mercury 3g modem with AT&T service which is provided for me my one of my clients. As far as I know there is no login information required for it. I got it...

If you don't want to reinstall, you can also run the PAE kernel, which will limit the size of a single process to under 4GB, but multiple processes can make use of 8GB or more of memory. This is...

Can anyone running Ubuntu on an M6500 confirm which SATA driver is loaded? Is it AHCI? Does the driver or lspci tell you what the chipset is?

Thanks,
