definitely not. The softirq.c:206 bug cannot be caused by any hardware
bug, unless the bug triggers memory corruption exactly in the
tasklet->state word (which sounds unlikely since different people
triggered the bug using different binary kernels that are unlikely to
allocate t->state exactly in the same place).
