Flushed with the success of getting today's -CURRENT running on my build system: freebeast[8] uname -a FreeBSD freebeast.catwhisker.org 5.0-CURRENT FreeBSD 5.0-CURRENT #16: Thu Aug 30 09:12:22 PDT 2001 root@freebeast.catwhisker.org:/common/S3/obj/usr/src/sys/FREEBEAST i386 I proceeded to do likewise with my laptop. However, that machine needed a little more assistance, so I'm sending this note out to provide a clue for others who might be similarly situated. The mainstream laptop to which mine is most similar is a Dell i5000e; it's actually made by Compal (who makes them for several vendors); details on the machine may be found at http://www.catwhisker.org/~david/FreeBSD/laptop.html. The symptom is that during boot, after the acpi.ko module is loaded, the boot process hangs, with the last several lines (in verbose mode) displayed being: pci_open(1): mode 1 addr port (0x0cf8) is 0x80003904 pci_open(1a): mode1res=0x80000000 (0x80000000) pci_cfgcheck: device 0 [class=060000] [hdr=00] is there (id=71908086) Using $PIR table, 7 entries at 0xc00fdf50 npx0: <math processor> on motherboard npx0: INT 16 interface acpi0: <COMPAL N38W2 > on motherboard A brute-force circumvention is to do an "unset acpi_load" before you get to that point, but that rather defeats the purpose. (It's still useful to know about it, though.) A slightly less brute-force approach (from a note that John Baldwin sent out to -mobile back on 22 Feb 2001) is to place the line debug.acpi.avoid="_SB_.PCI0.PX40.SIO_" in /boot/loader.conf -- and that done: m147[4] uname -a FreeBSD m147.whistle.com 5.0-CURRENT FreeBSD 5.0-CURRENT #107: Thu Aug 30 11:16:02 PDT 2001 root@m147.whistle.com:/common/C/obj/usr/src/sys/LAPTOP_30W i386 (Now to research ways of achieving the functionality I had with APM....)
