https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D233863 --- Comment #26 from Mark Millard <marklmi26-fbsd@yahoo.com> --- (In reply to Mark Millard from comment #25) Hmm. DSI at moea_pvo_find_va+0xec (non-debug kernel example): <moea_pvo_find_va+0xd0> bl 0054da44 <__mtx_lock_sleep> <moea_pvo_find_va+0xd4> rlwinm r11,r26,2,0,29 <moea_pvo_find_va+0xd8> lwz r9,-32744(r30) <moea_pvo_find_va+0xdc> lwz r9,0(r9) <moea_pvo_find_va+0xe0> lwzx r29,r11,r9 <moea_pvo_find_va+0xe4> cmpwi cr7,r29,0 <moea_pvo_find_va+0xe8> beq- cr7,0098a71c <moea_pvo_find_va+0x150> <moea_pvo_find_va+0xec> lwz r0,52(r29) which looks like: mtx_lock(&moea_table_mutex); LIST_FOREACH(pvo, &moea_pvo_table[ptegidx], pvo_olink) { if (pvo->pvo_pmap =3D=3D pm && PVO_VADDR(pvo) =3D=3D va) { It appears that the problem is seen at a common type of code structure that is not factored out. --=20 You are receiving this mail because: You are the assignee for the bug.=
