Summary: hangs on calling \_SB_.BAT0._STA on MaxSelect A7wide
Kernel Version: 2.6.11
Status: NEW
Severity: high
Owner: acpi_aml-interpreter at kernel-bugs.osdl.org
Submitter: vsu at altlinux.org
Distribution: ALT Linux
Hardware Environment: MaxSelect A7wide notebook (AMD Mobile AMD Athlon(tm) XP
2500+, SiS 746 chipset)
Kernel 2.6.11 with ACPI enabled does not boot on this machine - it hangs after
printing "Executing all Device _STA and_INI methods:...". Booting with
acpi_dbg_level=0x2f shows that it hangs on calling the \_SB_.BAT0._STA method.
Kernel 2.6.10 booted on this machine without problems. 2.6.11 with ACPI parts
(drivers/acpi/*, *include/*acpi*, drivers/pnp/pnpbios/core.c) reverted to 2.6.10
versions boots without hang.
2.6.11 with
http://www.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/release/2.6.11/acpi-20050309-2.6.11.diff.bz2
was tried - it hangs the same way.
Booting 2.6.11 with acpi_dbg_level=0x3f shows an endless stream of these messages:
exregion-0294 [30] ex_system_io_space_han: system_io 0 (8 width)
adress=000000000000006c
exregion-0294 [31] ex_system_io_space_han: system_io 1 (8 width)
adress=000000000000006c
The hang seems to happen in this loop inside \_SB.PCI0.LPC0.PMRD:
While (RCMD (0x80, Local0))
{
Noop
Noop
Store (PMUC, Local5)
If (And (Local5, 0x01, Local2))
{
Store (PMUD, Local5)
}
}
(other loops seem to have timeouts, but this does not)
