Accessing /afs from FreeBSD Linux emulation

[Resend, since the first one is in moderation for a few days now.]

On 10.3-RELEASE/amd64, I just tried to access /afs from the Linux
emulation on a remote machine -- now that machine does not even react to
ping anymore. I reproduced part of the problem locally on another machine:

/compat/linux/bin/bash
ls /afs

The (Linux) ls process consumes a whole CPU core, outputs nothing, and
is unkillable. Of course, /afs is busy and I cannot umount it, either,
making a clean shutdown of the machine impossible.

On one machine, it was a 64bit Linux environment
(linux_base-c6_64-6.7_1), on the other, it was a 32bit Linux environment
(linux_base-c6-6.7_1).

Is accessing /afs from the Linux emulation supposed to work?

Thanks,
