 there are at least two separate reports of the following log sequence:

 {{{
 [1147916.862327] ehci_hcd 0000:00:0f.5: HC died; cleaning up
 [1147916.912830] usb 1-4: USB disconnect, address 4
 [1147916.913381] eth1: unregister 'asix' usb-0000:00:0f.5-4, ASIX AX88772
 USB 2.0 Ethernet
 }}}

 in my case, the laptop had been up for 2 weeks, with only one external USB
 device was attached (wireless disabled).  external device was an XO-
 branded asix ethernet dongle. kernel was debxo 0.3 kernel:
 {{{
 Linux serviceberry 2.6.25.15 #147 Mon Oct 27 09:45:50 EDT 2008 i586
 GNU/Linux
 }}}

 i believe i've seen this several times before, as well, with an SMC enet
 adapter, also an asix (ASIX AX8817x), but at the time i didn't save logs
 when things went bad.  in my case failures have always occurred after days
 or weeks of uptime.


 in IRC user svu's case, running build 800 (8.2.1), the system had been up
 "probably half a day".  external ethernet device was asix, also had a
 serial USB dongle attached:
