Subject: more infos about kernel panic fujitsu
Date: Sun, 07 Sep 2003 17:34:11 -0400 [thread overview]
Message-ID: <3F5BA453.7010200@mlkj.net> (raw)
Hi,
I have more infos about the kernel panic experienced on Fujitsu E7010
series laptop when ACPI is enabled.
(see http://www.ussg.iu.edu/hypermail/linux/kernel/0307.2/0713.html )
(kernel-2.6.0-test4)
The kernel crash in resource/nsutils.c line 740 :
if (ACPI_GET_DESCRIPTOR_TYPE (handle) != ACPI_DESC_TYPE_NAMED) {
because handle == 7 and
#define ACPI_GET_DESCRIPTOR_TYPE(d) (((union acpi_descriptor *)(void
*)(d))->descriptor_id)
this value is set in resource/rsmisc.c line 95 function
acpi_rs_end_tag_resource:
output_struct->id = ACPI_RSTYPE_END_TAG;
in resource/rslist.c function acpi_rs_byte_stream_to_list
output_buffer (= output_struct) is changed to the same value than handle
Since I don't see how to fix the code, I have this ugly workaround :
in pci_root.c line 294:
handle = device->handle;
acpi_pci_evaluate_crs(root);
device->handle = handle;
handle = NULL;
