Description Newfie 2011-08-26 21:00:13 UTC
I first used unetbootin on Fedora 15 (64 bit) to create a live USB for Fedora 16, also 64 bit. I booted the Live USB on my computer and it functions just fine. However, when I mount a second USB drive and try to copy files from it (tried with a FAT and NTFS drive) to the Fedora 16 live USB session, I get a kernel panic. The file transfer works fine until near the end; this is when the screen turns black and some errors pop up in a TTY followed by "kernel panic". Just for clarification, F16 has not been installed and this is entirely on a live USB. I have remade the F16 USB image on 2 different machines (running different distros) and on 3 USB drives; all have the same result, and the panic occurs on both of my computers.

Using the Live CD image of Fedora 16 Alpha x86_64 as advertised on Fedora's main page.

Reproduction is 100% consistent for me.

Steps to Reproduce:
1. Create a Fedora 16 live USB image.
2. Boot and log in to the F16 live session.
3. Mount a usb drive (thumb drive, etc)
4. Copy any file from the USB drive to any directory on F16.
5. Wait for panic.
Actual results: Kernel panic

Expected results: Should just copy the file(s).

Thanks, and good luck.

Can you post the panic message including the full backtrace?  If the machine is unresponsive and you can't use it to attach dmesg, using a camera to take a picture of the panic on the screen can help.

There's a weird thing going on right now; I can't seem to reproduce the panic.

When I was trying this yesterday, I was repeatedly attempting to copy some files over just so I could test stuff out on Nouveau. Each and every time there was a kernel panic. Yet right now, everything is copying just fine. These are the same USB drives and machines as I was using before; no idea why it's suddenly working, especially since it's a live session without persistence.

Closing as NOTABUG; you can reopen this bug if it starts happening again.
