From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5) Gecko/20031007 Firebird/0.7 Description of problem: I'd like to apologise for the lack of information in the report. This is due to me not knowing how to troubleshoot this. Any help would be appreciated. I have an Iomega USB Flash drive. It has a capacity of 128 MB. I'm running a computer with USB 1.1, and the Flash drive is USB 1.1, not 2. When I mount the flash drive, using mount /dev/sda1 /mnt/flash, the drive mounts fine. The drive is formatted as vfat. The problem comes sometimes when I try to copy to the drive. Nothing happens. No lights on the drive flash, and no feedback from cp. Killing with kill or kill -9 on the cp, as normal user, or as root fails. No entries are in /var/log/messages I cannot unmount, or force an unmount of the drive as root. A sync as root hangs. lsof does show the copy. Switching down to runlevel 1 still shows the non-root owned cp process. How reproducible: Sometimes
This is a kernel issue.
I still get this problem sometimes. The problem is less likely to occur if I've recently formatted the flash drive. poweroff seems possible if the machine is kept on for a time (an hour or more) after the problem.
I can't narrow down this one to produce a test case, so closing.
