ACPI315PRE.ZIP also traps the system at shutdown with the kernel debugger. This is a T42.

Photo of screen?

[ecsnl]

This trap happens with the kernel debugger. So the output is on the debug terminal with pmdf.exe. The last output is the debug kernel that catches an exception. As in http://svn.netlabs.org/acpi/attachment/ticket/381/PSD_RESET_MODE_trap.txt There is not output on the screen of the laptop since the exception handler sends the trap to the serial port.

[pasha]

Give me log, screen, any what you can give. String, were was previous trap is absent in acpi,psd, you can look it in svn.
