hi, kernel does not panic, so I cannot dump kernel. And I saw message "kernel trap 9 with interrupts disabled" on the console. So I built kernel with kdb and ddb, and I did single stepping execution with break point at printf. At doreti_iret_faut, db> s Stopped at doreti_iret_fault: subq $0x98,%rsp db> s Stopped at doreti_iret_fault+0x7: testb $0x3,0xa0(%rsp) db> s Stopped at doreti_iret_fault+0xf: jz doreti_iret_fault+0x14 db> s Stopped at doreti_iret_fault+0x11: invlpg %ax db> s not return... Keyboard(num lock or caps lock) does not react. What should I do? -- tadokoro
