Description Peter Lister 2003-10-10 19:53:41 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030225

Description of problem:
The acpi/* modules refuse to load, as described below. Other modules appear to
load fine. There is no relevant error text in dmesg or syslog.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
[root@localhost prl]# /sbin/modprobe battery

Actual Results:  /lib/modules/2.4.22-1.2087.nptl/kernel/drivers/acpi/battery.o:
init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including
invalid IO or IRQ parameters.
      You may find more information in syslog or the output from dmesg
/lib/modules/2.4.22-1.2087.nptl/kernel/drivers/acpi/battery.o: insmod
/lib/modules/2.4.22-1.2087.nptl/kernel/drivers/acpi/battery.o failed
/lib/modules/2.4.22-1.2087.nptl/kernel/drivers/acpi/battery.o: insmod battery failed
[root@localhost prl]#

Additional info:

There are no errors from depmod -a

When I cut an RPM of the kernel 2.4.22-20.9 kit, with APM disabled and ACPI
enabled, the corresponding ospm* modules built and could be loaded with modprobe
just fine (whether they worked is another matter, but they could be loaded).

I note that I'm having trouble with the i810_audio driver [Bug 106784], which
might be ACPI related, so it occurs to me to wonder if there is some more
general ACPI issue on this hardware.

Did you boot with acpi=on?

Comment 2 Daryll 2003-10-16 19:27:50 UTC
Same problem. I can't load battery or ac modules. It worked with version 2061
and started failing with kernel versions after that. This is an HP Pacillion Ze

Comment 3 Peter Lister 2003-10-16 20:14:12 UTC
Sigh. No, I've now set up acpi=on and it all works (so does i810_audio, bug ),
so I feel a bit stupid.

In my defence, I *did* try to search for similar problems, but as I saw quite a
few ACPI messages on start, it wasn't obvious to me that ACPI was off by
default. The modules don't fail with a helpful reason...

So  I guess you can close this as a dup, but hopefully some others will find
this particular entry before wasting a day or two...

Comment 4 Peter Lister 2003-10-16 20:15:11 UTC
And bug 106784.

Comment 5 Daryll 2003-10-16 20:31:31 UTC
acpi=on works for me. Helps if you put it on the correct line in your grub.conf. :(
