I was working on getting unmenu going, and sudden all of the files disappeared from underneath me. Looking around, I noticed the whole /boot directory was now empty, but still mounted. I'm working remotely on it right now, so not sure if the usb key needs to be moved to a different spot (its plugged directly to the mb, not a front spot. No other usb devices at all).

 

 

It looks like it lost contact with your flash drive, so the contents of the mount point /boot would disappear, just as if you had pulled the drive.  If you did not touch the drive, then I would consider that USB port unreliable, and find another.  A reboot should give you a fresh, rebuilt system.

Well, did a reboot and she disappeared. I'll have to check when I get home in a few hours. 

On a side note, yesterday I rebooted remotely from work, and she disappeared on me. When I got home, it had booted up just fine, but failed to mount the flash drive, so it had none of it configs.

... or network access.

 

I'd be looking for a more reliable USB port to plug into.

I can now reliably duplicate the problem. I got home and the server wasn't booting because it thought the usb drive was ejected. Power down, reboot, all is well. I began doing the EXACT steps I was doing this morning and again, it caused the usb drive to disappear.

 

For some reason it appears the kernel is actually reseting (and failing) the usb drive, and then ejecting it.

Steps I can do to repeat this:

 

I have 1 share only, The ONLY thing on it so far is the 3 unzipped archives for unmenu. I unzipped them on my windows machine and dropped them on the share so I could move them into place.

 

I telnet in, cd /boot. Do an ls, and I see everything just fine. My unmenu dir is still there, I cd to it. now I do 'cp /mnt/disk1/Movies/* .'

 

I do an ls immediately and I see all of the files. I attempt ./uu and I get no such file or directory. Another ls shows that no files exist any more. A quick check and there is NOTHING in /boot anymore and the logs show that the drive was ejected.

 

I've repeated this multiple times now, it doesn't matter what port the usb is in either.

Looks like it's a ehci module bug. http://taint.org/2006/12/13/191554a.html#comment-1845

 

I've seen a lot of posts across all flavours of linux showing the same bug, This makes sense in my case sense I'm copying ALL of the unmenu files at once, and they are small. I'll try turning off USB 2.0 support in my bios and see how that affects things.
