I have an HP DL380 running 5.3 and it will not reboot from multi-user mode - it hangs after printing "Rebooting..." and needs to be power- cycled (since there's no reset button). This doesn't happen with 4.10 or in single-user mode. ACPI and BROKEN_KEYBOARD_RESET make no difference. Adding some printf's in the shutdown sequence shows that the code is getting to the keyboard reset or invltlb() correctly. The big difference between 4.10 and 5.3 is ACPI - but disabling it doesn't have any effect. Does anyone have any ideas for where to search next? Working through /etc/rc.d would be a long and painful process since the POST takes a couple of minutes. BTW, would someone like to either explain or provide a pointer to how zeroing the page table and wiping the TLB resets a PC. I would have expected the CPU to wedge when it can't access memory (it can't take an exception because it can't save the state or fetch the exception descriptor). -- Peter Jeremy
