FAQ has a reference to it. But thanks for reporting the bug.

thanks - the key bit to start with is GR02 and IOAQ :

GR02 0x101e3910 nfs_mark_request_dirty+24
IOAQ 0x1010c1b0 intr_restore+11c

Sounds like either an interrupt storm from the card or a deadlock
in nfs code. Unfortunately TOC doesn't provide more stack trace
informaion. And I'm not able to chase NFS issues at the moment.
