pnpbios oops on boot w/ 2.5.47

pnpbios oops on boot w/ 2.5.47

[Justin A]

[-- Attachment #1: Type: text/plain, Size: 405 bytes --]

Hi :)

I tried to "port" kmsgdump to 2.5.47 and for some reason, it worked.

Attached is the full dmesg

Alan: I ran dmidecode under 2.4.19 which said simply "PNP BIOS present"

This is a thinkpad 760e, really old..I don't even think I need pnpbios support 
for anything.  2.5.47/2.5.47-ac5 boot with pnpbios turned off, so I think you 
just need to add this to your blacklist?

The BUG in slab indicates that something overran the end of a kmalloced
buffer.  That'll be either pnp_bios_get_dev_node() or node_set_resources()
ran off the end of `node'.

err...

        node = pnpbios_kmalloc(node_info.max_node_size, GFP_KERNEL);

max_node_size appears to never be initialised.

If it was calling pnpbios_set_resources you probably do.  This means it was
trying to activate a device.  If a device is not active you cannot use it.
This device was most likely a serial port or modem.  Try turning on PnP
Debug after applying the below patch and see if a device is activated.

Oops.  I put the pnpbios_kmalloc in the wrong place.  It's amazing it still 
worked on my test box.  Here's a patch that should fix it.  Justin: could you
please try it.

Thanks,
Adam

The typo appears to be in pnpbios_set_resources.  Andrew: Is this where you 
found it?

As far as I can see, max_node_size is never initialised anywhere.

It may not appear to be initialized but in reality it actually is.  pnp_bios_dev_node_info
recieves a pointer to the node_info structure containing max_node_size.  It then passes the
pointer to __pnp_bios_dev_node_info which then passes the pointer to call_pnp_bios.
call_pnp_bios is in assembler primarily and writes data directly to the pointer almost as if
it were a buffer.  As a result the structure contains a value for max_node_size.

I appreciate your input.  Let me know if you need any additional information.

Thanks,
Adam

Re: pnpbios oops on boot w/ 2.5.47

[Alan Cox]

There is at least one other problem. The pnp layer is initialized way
too early. I've moved pnpbios and isapnp to init after acpi and pci in
my tree and at least one weird oops on Telsa's Cyrix MediaGX + CS5520
box has gone away.

Now to figure out how I broke IDE ;)

I had a fealing that call_pnp_bios was doing something with data so I tried it 
anyway with:

CONFIG_PNP=y
CONFIG_PNP_NAMES=y
CONFIG_PNP_DEBUG=y
CONFIG_ISAPNP=y
CONFIG_PNPBIOS=y

and it booted ok.  You were right, it was a serial port(even though that port 
always worked without pnp:))

I didn't have NAMES and DEBUG on before, so hopefully neither of those is what 
fixed it in this case.

Here is the new dmseg, you can ignore the crap at the end, thats just pcmcia 
being broken, it goes away if I move /l/m/2/k/d/pcmcia out of the way.

Hmm, this isn't right.  0x85 means unable to set resources.  If you have it 
could you please send me a copy of the output of lspnp for node 13.  I'm not
sure what this device is, do you have a second serial port?

Thanks,

lspnp output at the end.

It has 2 infrared ports(well its the same port in 2 places....) , one rs232 
port on the back, and a modem port.

This is an IBM thinkpad, so imagine BIOS from hell, its all gooey and 
useless...  I think you are supposed to be able to switch the serial port 
from infrared to the rs232 port, but I don't know how.  I use the infrared 
anyway so thats ok :)

It might be flipping out over the modem, its one of those mwave DSP things.  
Neither the modem or the sound work in linux right now... I would need to 
install http://www-124.ibm.com/acpmodem/ to get just the modem working..and I 
really don't even care :)

If anything I would like the sound to work.  I think once its initialized it 
ends up being sb compatible, but I think even then its only 8bit sound, which 
isn't even worth it.

even after 
"PnPBIOS: set_dev_node: Unexpected status 0x85"

The IR port still works, so it doesn't seem to break anything...
