Summary: Hard lock while booting Acer Aspire 1310 with kernel
since 2.6.32 and acpi activated
Product: ACPI
Version: 2.5
Kernel Version: 2.6.32 up to 2.6.37
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: EC
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Regression: Yes
I'm using an Acer Aspire 1310 notebook for several years and never had a
problem with ACPI. But since update to kernel 2.6.32 I cannot longer boot with
acpi on. I've tested several acpi settings. Only with acpi=off (or acpi=ht with
kernel < 2.6.37) is able to boot.
After several help on <https://bugzilla.novell.com/show_bug.cgi?id=623393>
(many thanks to Rafael Wysocki) we found out, that the 35th call of
acpi_init_one_device does not return from acpi_ns_evaluate. If I add some crude
code to acpi_init_one_device to immediate return with
return_ACPI_STATUS(AE_CTRL_DEPTH) from 35th call of acpi_ns_evaluate, kernel
2.6.37 boots!
You may find more information, e.g., several attachments like acpi dump, screen
photo of the hard lock, outputs of dmesg, lspci, and dmidecode on
<https://bugzilla.novell.com/show_bug.cgi?id=623393>.
