Kernel messed up

stepan_par · 07-11-2007, 08:53 AM

Hi guys. When i installed Debian and booted into my Intel core 2 duo e6300 machine with 2 gb of ram using acpi=off(i have to do this with every distro except ubuntu), all my usb slots were not responsive. This has been happening in every distro except ubuntu. What can i do to solve this problem? i was wokring in my ubuntu box and decided to compile a kernel as well , and when i used the kernel , the same problems occurred! COuld you tell me what is the difference by debian kernel , pclinuxos kernel , my compiled kernel to the ubuntu kernel? What do they do to it that makes my pc work.. I should mention that all my usb slots are usb 2.0 . if you want to know a compelte list of my hardware , i am using an hp pavilion a1640n.

Which version of ubuntu works?
Probably they have made a patch to either not read the buggy (or not_as_expected) ACPI information or change the expected mechanism. Or they patch the acpi information on the fly at every reboot.

That's what I'm talking about:

Then you run 2.6.20?
This is what is added by ubuntu to the kernel 2.6.20

Did you try
pci=noacpi
or
acpi=noirq

rather than acpi=off
?

There's also this for debugging (depending on the time you have and interest in debugging..) then you would forward it to a kernel team.. (good luck..)

Code:

	acpi.debug_layer=	[HW,ACPI]
			Format: <int>
			Each bit of the <int> indicates an ACPI debug layer,
			1: enable, 0: disable. It is useful for boot time
			debugging. After system has booted up, it can be set
			via /sys/module/acpi/parameters/debug_layer.
			CONFIG_ACPI_DEBUG must be enabled for this to produce any output.
			Available bits (add the numbers together) to enable debug output
			for specific parts of the ACPI subsystem:
			0x01 utilities 0x02 hardware 0x04 events 0x08 tables
			0x10 namespace 0x20 parser 0x40 dispatcher
			0x80 executer 0x100 resources 0x200 acpica debugger
			0x400 os services 0x800 acpica disassembler.
			The number can be in decimal or prefixed with 0x in hex.
			Warning: Many of these options can produce a lot of
			output and make your system unusable. Be very careful.

	acpi.debug_level=	[HW,ACPI]
			Format: <int>
			Each bit of the <int> indicates an ACPI debug level,
			1: enable, 0: disable. It is useful for boot time
			debugging. After system has booted up, it can be set
			via /sys/module/acpi/parameters/debug_level.
			CONFIG_ACPI_DEBUG must be enabled for this to produce any output.
			Available bits (add the numbers together) to enable different
			debug output levels of the ACPI subsystem:
			0x01 error 0x02 warn 0x04 init 0x08 debug object
			0x10 info 0x20 init names 0x40 parse 0x80 load
			0x100 dispatch 0x200 execute 0x400 names 0x800 operation region
			0x1000 bfield 0x2000 tables 0x4000 values 0x8000 objects
			0x10000 resources 0x20000 user requests 0x40000 package.
			The number can be in decimal or prefixed with 0x in hex.
			Warning: Many of these options can produce a lot of
			output and make your system unusable. Be very careful.

Any google search on acpi and pavilion?
or pavilion and dsdt?

thank you!could you tell me how to install the http://archive.ubuntu.com/ubuntu/poo...-16.29.diff.gz ,do i install it like a patch? Man i cant be more grateful. The ubuntu guys wouldnt give me anwsers o nthe forums because most of them are new to linux.

--- i tried you boot options , non worked but i searched around and found out that i was supposed to use pci=nommconfig . i do still want to know about the patch though

You download linux kernel 2.6.20.? (should be mentionned on which kernel.org version it applied) and you apply this patch and you should get the ubuntu-modified kernel source.
