Bug#644279: linux-image-2.6.38-bpo.2-686: Disabling IRQ 10 hang and crash laptops, ALL KERNELS on squeeze & backports
News from my laptop..
LISTEN CAREFULLY: This is a complex but solvable technical problem
from software, just have to disable the misuse of power by the ac
module related to batery and dual-core CPU subsystem
this problem knows as
...--->>>>>". the famous freeze when ac power cord it's plugged"<<<<---....
affects all toshiba laptops models a205-XXXX (when XXXX are any number
of course), my model are satellite a205-S4607 as report in this bug
topic previosly
NOTE IMPORTANT, in some boot up's the kernel detects "buggy bios" and
suggest pass "pnpbios=off" to the kernel command line..
, i note that for this problem i must pass **again** "acpi=off" to
the kernel command line for work, so
now i instaled 3.2 kernel and the "irq nobody care" dissapears.. so
some code "works around" the olders kernels..
but surprise guys, this its not kernel linux problem or not kernel
bug!!!!! but someway , 3.2 linux kernel work around part of problem...
Now I report that the machine the problem was not in the kernel, but
this is solvable, performing a simple test, write a code that tests
the BIOS .. depending on the version and disable the powermanager, and
regulation of power consumption of the CPU and Batery , theres a two
solutions here:
http://forums.toshiba.com/t5/Batteries-and-Power/Solutions-Laptop-will-only-run-on-battery-freezes-when-the-AC-is/td-p/178572
one of these could manage throught linux kernel..
I try to dumb a bin file of bios and solve this out of kernel, using
dmidecode and dumbbios tool with my massenkoh linux emergency iso..
please if knows any people that solve this bios error let me nkow
the 3.2.0 kernel work well on acpi enabled, but, toshiba laptop hangs
at few minuts, only if power cord are plugged, or if u plug cord when
power on., now kernels runs with ac power cord unpliugged with kernel
3.2 fine and acpi activated (just passed acpi_resource_enforces=lax
for activate some devices and all fan)! i revised what changes where
made but i not a kernel mainline knower so i dont know where to
start.. but just now i have revised acpi code of kernel 3.2
