Probably the same bug as seen > on other archs - die on first fork. The last problem happens only on r4000 and r4400, and occasionally also shows up as "illegal instruction" or "unaligned access". It turned out to be a broken TLB handler. I temporarily switched (for 32bit kernels) from except_vec0_r4000 to except_vec0_r45k_bvahwbug. This may cause an avoidable performance loss, but at least it allows my R4400SC-200 (V6.0) Indy to run current 2.6 CVS. Thiemo
