System : OpenBSD 5.4
Details : OpenBSD 5.4-beta (GENERIC) #21: Tue Jul 9 11:45:27 MDT

Architecture: OpenBSD.i386
Machine : i386
>Description:
The following panic occurs at random intervals on an alix2d3
while rsyncing data from an ffs on sd0 (umass0) to an msdos
partition on sd1 (umass1). rsync is called via hotplugd
when attaching umass1. It does not occur when only accessing
one USB disk.

>How-To-Repeat:
Copy data between usb disks. The system will panic after
some time. Most of the time, 1GB is enough for it to panic.
>Fix:
Fix unknown. The panic() was introduced in rev 1.59 of ehci.c.
