Well, my functional programming teacher at the university is
experiencing this bug (& resorted to using wl in the meantime -
machine is a Lenovo S10e), but I don't know how well he understands
the Linux kernel (given that it's not written in Haskell). But I'll
write back if I find out anything. In the meantime, keep on searching.
