For a couple of days, I have been consistent panics whenever I mount
an NFS filesystem on a newly made -CURRENT. Things seem to work fine
when NFS is actually built into the kernel. But when mount(8) is auto
loading the nfsclient.ko module, I get an immediate panic when
something actually tries to access the filesystem,

#0 0xc01b6b8a in dumpsys ()
Is this a known issue (I haven't noted mention of it on here) or does
someone want to see some more debugging info?
