alpha hangs switching VC -- 2.1.115

When running X, I try to switch out of it with Ctl-Atl-F1 and my machine
hangs, completely. I have enabled SysRq support, and even that doesn't
unjam (or even reboot) my machine. I had the same problem with 2.1.111
as well.

Some details:

icarus.com % uname -a
Linux icarus.com 2.1.115 #15 Fri Aug 14 14:54:24 PDT 1998 alpha unknown
icarus.com % /gnu/test/bin/gcc -v
Reading specs from /gnu/test/lib/gcc-lib/alphaev5-unknown-linux-gnu/egcs-2.91.51/specs
gcc version egcs-2.91.51 19980714 (gcc2 ss-980609 experimental)

I do not have frame buffer support specifically enabled. Should I?

I also have a module that allocates/reserves pages. When I unreserve/release
that memory, I get exactly the same hang. (This driver worked fine on 2.1.109,
and works fine on 2.0.x kernels.) Could this be at all related?

.config available on request.
