Hi all,

I'm trying to install 2.4.1 release on laptop Dell E6400. I have problems to
install FreeBSD or DragonflyBSD on it for about last 6 months. Everytime kernel
panic and I end in ddb, but keyboard is not working then. I can use this Live CD
or install it on hdd when I disable ACPI. In NetBSD or OpenBSD it's working and
on OpenBSD suspend/resume is not running.

I can't post much more details. Just what you can see in attachment as keyboard
is not working and I don't have serial console or USB -> RS232 converter.

Which version of FreeBSD have you tried, 7.2 or 8.0?


Updated by bodie over 11 years ago

7.2 and some 6. Can't remember exactly now. But no one was current.

Try to drop into loader prompt and set debug.acpi.disabled="cmbat".


Updated by bodie over 11 years ago

set debug.acpi.disabled="cmbat" is working at least for installer. I'm
installing now to test other bugs.

Hmmm, after installation when I'm going to boot from disk trough CD installer
after these steps in loader prompt : unload ; lsdev ; set curredev="disk0s2a" ;
set debug.acpi.disable="cmbat" ; boot I get again kernel panic on attached
screenshot and keyboard is not working.
