Hello,

like I already described in another mail some weeks ago on my Samsung
Q35 notebook cards inserted into the pcmcia slot do not get powered=20
with a kernel newer than from january.=20
I now selected the option "Boot FreeBSD in Safe Mode" and the card is
powered and recognized.
After playing around in beastie.4th, disabling the entries
hint.acpi.0.disabled
loader.acpi_disabled_by_user
hint.apic.0.disabled
are causing the card to work.

However, it does not work when I select "Boot with ACPI disabled".

"Boot with ACPI disabled" only disables ACPI. Safe mode also disables
APIC.

Does the system boot correctly in safe mode? Does it boot with only APIC
disabled but ACPI enabled?


Yes, it boots correctly with only APIC disabled and ACPI enabled. But
then I again have the cardbus problem.

So it always boots ok? Which combinations of ACPI on/off and APIC on/off
allow the cardbus card to work?

Now the situation is:

ACPI enabled, APIC enabled: works fine
ACPI disabled, APIC disabled: not recognized
ACPI disabled, APIC enabled: not recognized
ACPI enabled, APIC disabled: not recognized

I also encountered occasional "Panic: failed to create swap zone" when
CPU #1 was launched just before the disks get mounted. Could that be
related?

Lars
