bug report: Pegasus USB Ethernet driver, SNMPd, and kernel errors

[Michael Rothwell <michael@rothwell.us>]

I'm using a Linksys USB-Ethernet adapter (ADMtek AN986 "Pegasus") on  
a 2.6.15-1.1833_FC4 system (if this is an inappropriate place to  
report this bug, let me know, and my apologies).

I am running snmpd on that same system. A very short while after  
snmpd is started, the kernel begins to log errors related to the  
pegasus driver. It does not log these errors if snmpd is not running.  
The errors seem to be triggered by snmpd's polling of the machine's  
network interfaces. Once the errors begin, snmpd hangs in an  
unkillable state until the machine is rebooted.

Sample of errors:

Mar 13 18:43:41 kronk kernel: pegasus: v0.6.12 (2005/01/13), Pegasus/ 
Pegasus II USB Ethernet driver

I love that Linksys' shipping product uses an "evaluation board".
