I finally got around testing this patch on today's RELENG_5. I built
my custom kernel (mostly based on GENERIC but with ehci), booted that,
copied the kernel to an 16 MB sdcard i had lying around using an usb
multi-cardreader, which worked. umounted, disconnected, reconnected,
mounted again and verified the kernel, which worked as well. Then I
noticed this in dmesg:
da3: 1.000MB/s transfers
so it wasn't using ehci apparently. I thought, maybe this is
intermittent too like with my externally powered devices, so I
disconnected and reconnected again, but this time da3s1 didn't appear.
(dmesg also shows da1, sometimes with 1 and sometimes with 40 MB/s,
but I never saw a /dev/da1s1 appear.) I wanted to try again, and when
disconnecting I got the following panic:

Thats doesnt tell me much tho. This is dmesg extracted from the dump,
