[Click] Unable to handle kernel paging request at virtual address

[Paine, Thomas Asa]

Ok, I started a long email but soon realized it would be confusing as
hell, so let me try the quick and dirty post first :)

	I'm getting oops, with EIP always pointing to HashMap.insert.
However, the call trace can differ (somewhat) and the top of the call
trace is not always in a method using HashMap.insert (.find though).
Eliminating calls seen in the trace seems to have no affect on
preventing an oops.  Are there any open issues/changes with HashMap?  Is
this a memory allocation error?  Possible incorrect kernel setting?
Anyone have troubleshooting recommendations for this error?  I've
attached my current kernel config for 2.6.16.13.  I'm not 100% sure this
has anything to do specifically with hashmap, or if it is just hashmap
manifesting the error, for whatever the real reason might be.  

Looking for some guidance, thanks.
