実は必ず tlp0 overrun とか出るので、
割込を止めている間に来たやつが machine check を起こすのでは ?
ということは tlp 側の処理の問題かも知れない。
あるいはこちらが長く止めすぎているとか。
そう言えば、bt の時の stack の表示が少ないのは、
in real mode on a separate stack, のせいか。

pteidx と ptemach は inline になっている:
187 static inline int
188 ptematch(ptp, sr, va, which)
189 pte_t *ptp;
190 sr_t sr;
191 vaddr_t va;
192 int which;
193 {
194 return ptp->pte_hi
195 == (((sr & SR_VSID) << PTE_VSID_SHFT)
196 | ((va >> ADDR_API_SHFT) & PTE_API)
197 | which);
198 }
