Tons of "BUG: dst overflow ..." messages

Just logged into my router, which is running 2.6.9-rc2-bk1 (or -bk2, not 
sure), and saw a buttload of the following messages:

[jgarzik@pretzel g]$ dmesg -s123000 |grep -c BUG
488

[jgarzik@pretzel g]$ dmesg -s123000 |grep BUG|sort|uniq
BUG: dst underflow 0: cf5dd180 at f8c0be5d
BUG: dst underflow 0: cf5dd180 at f8c0d15c
BUG: dst underflow 0: cf5dd180 at f8c1656f


router seems to be working fine regardless of these BUGs.

ifconfig, .config, and lspci attached.

Is this a known, already-fixed issue?
