In Sage 4.7.1:
{{{
sage: K = GF(4,'a')
sage: a = K.gens()[0]
sage: R.<x,y> = K[]
sage: p=x^8*y^3 + x^2*y^9 + a*x^9 + a*x*y^4
sage: q=y^11 + (a)*y^10 + (a + 1)*x*y^3
sage: p.factor(proof=False)
x * (x^7*y^3 + x*y^9 + (a)*x^8 + (a)*y^4)
sage: q.factor(proof=False)
y^3 * (y^8 + (a)*y^7 + (a + 1)*x)
sage: f = p*q
sage: f.factor(proof=False)
}}}
The last command seems to hang forever.
