Re: Kernel with acpi hangs on compaq presario 1700

Re: Kernel with acpi hangs on compaq presario 1700

[Heiko Ettelbrueck]

Hi Jaap,

if you don't want to use ACPI because of its IRQ routing, you could 
simply try adding "pci=noacpi" at the boot prompt (or into lilo.conf / 
grub's menu.lst) for your acpi kernel and try once again. I have a 
Compaq Evo N160 and had the same problem (hang during boot) before I 
tried the above kernel option.

I also got the advice to disable "Local APIC" and "SMP Support" in the 
kernel configuration, but this didn't help in my case. Perhaps it will 
in your one?

Regards,
Heiko

Kernel with acpi hangs on compaq presario 1700

[Jaap Hogenberg]

Hi,

I'm new to this list so forgive me if this is a FAQ:

I'm tried kernel 2.4.20 with the acpi patches of 12052002 and 12122002
as well as a 2.5.51 with and without patch (12132002) and when I include
acpi support , the kernel will hang when probing the PCI bus.

I have seen references about acpi on compaq laptops indicating that it needed
some tweaking (dumping acpi tables to a file) but as these were 
very old postings to linux-kernel mailing list , and the answers there
were quite inconclusive I thought I'd ask here.

Is there some (recent :-) ) documentation on getting acpi working
on this laptop ? 
Or is there anything else I should try in my kernel config ?

Regards,

Jaap

empty directories under /proc

[Jörg Hänsel]

Hello,
I have a IBM R32 notebook and compiled a (clean) 2.4.20 kernel patched with 
the acpi patch from 12122002.
When I load the modules ac.o  battery.o  button.o  fan.o  processor.o  
thermal.o nothing is complaining. But when I look into /proc there is no 
subdirectory acpi, but subdirs from the ospm modules are directly under /proc

1     1359  1647  224  ac_adapter   fb           locks       stat
1285  1361  1655  225  battery      filesystems  meminfo     swaps
1286  1362  1663  226  bus          fs           misc        sys

1358  163   219   99   fan          loadavg      slabinfo

When I boot the kernel there is a message:
ACPI: Found ECDT
ACPI: Could not use ECDT

Can this be a reason for the problems.
Is there a Kernel config dependency I have overseen, an option that must be 
enabled for ACPI ?

please help,
Joerg

Re: empty directories under /proc

[Thomas Estaben]

It seems u have the same prob than me.
I have a thinkpad t30..
The problem come from a bad bios from IBM. Since there is no prob with acpi 
under windows, they will not release a good one.
Sad, very sad...
We have to wait, and to hope that someone find a workaround for this prob..

Yes , this works. But that presents me with another problem, upon
inserting pcmcia cards, I get the message "request IRQ:resource in use"
and  "resorce temporarily unavailable" messages.

Are there any other ways to set up the interrupt routing for this machine ?
Or should I try compiling all the drivers into the kernel instead of modules ?

Regards,
Jaap

Look at:
http://dude.noc.clara.net/~faye/compaq2701ea/
http://www.cpqlinux.com/acpi-howto.html

This 2 pages should give you a good understanding for the compaq in general,
and the first one for Presario 2701EA in perticular.

Please note also that Compaq have released new BIOS in the mean time
which should be more ACPI friendly, AFAIK.
