While testing other machines for PR kern/52440, I happened to boot a Gateway M-1625 laptop. At some point during boot, it appeared to hang and the LCD screen slowed faded to white.
After a few rounds of booting in userconf mode and disabling various things, the machine completed booting. 'dmesg' reveals the video card to be: [...] acpivga0 at acpi0 (VGA): ACPI Display Adapter acpiout0 at acpivga0 (CRT, 0x0100): ACPI Display Output Device acpiout1 at acpivga0 (TV0, 0x0210): ACPI Display Output Device acpiout2 at acpivga0 (LCD, 0x0110): ACPI Display Output Device acpiout2: brightness levels: [12,25,37,50,62,75,87,100] acpivga0: connected output devices: acpivga0: 0x0100 (acpiout0): Ext.

Rebooting normally, the problem seems to occur just after "/" is available and it tries to load firmware. The machine is stuck at that point and the screen has faded to all white. I can press Ctrl-Alt-Esc, get in to DDB, blind-type "reboot" and the machine reboots. -- |/"\ John D.
