Attachments: output of acpidump run with kernel 2.6.12-1.1398_FC4smp

Description Hubert Verstraete 2005-08-31 10:14:52 UTC 
Most recent kernel where this bug did not occur: 2.6.12-1.1447_FC4smp (which is
a 2.6.12 with acpi patch 20050729)
Distribution: Fedora Core 4
Hardware Environment: Acer Aspire T630
Software Environment: gcc-4.0.1-4.fc4
Problem Description:
The previous kernel 2.6.12-1.1398_FC4smp worked with ACPI loaded. It has the
acpi patch 20050309. I tried to recompile the kernel with the acpi patch
20050408 and it worked too. But now with the last acpi patch, I've got a failure
while initializing ACPI. Consequence ACPI is disabled, and some other problems
occur, like sata_uli modules which hangs; more info here:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=165103

I recompiled with ACPI debug; here's a bit of the output of dmesg:

Comment 3 Robert Moore 2005-09-01 13:12:30 UTC 
This DSDT seems to have the "executable code at module level" which is not 
currently supported by ACPICA, and results are unpredictable.

    Store (Buffer (0x03) {}, Local0)
    CreateByteField (Local0, 0x00, BUF1)
    CreateByteField (Local0, 0x01, BUF2)
    CreateByteField (Local0, 0x02, DMAM)

Versions of ACPICA beyond 20050513 cannot disassemble the DSDT, this is a 
problem also.

We are still investigating the solution for both problems.
Comment 4 Robert Moore 2005-09-01 15:21:51 UTC 
Problems with the support for module-level executable code forced us to 
disable the code. However, some of the support remained active, causing these 
problems. Fixed for the next ACPICA release. Also fixes the disassembler issue.
Comment 5 Robert Moore 2005-09-06 12:49:11 UTC 
Fixed in ACPICA version 20050902
Comment 6 Len Brown 2005-09-09 09:20:01 UTC 
Shipped in 2.6.13-git9.
Closing.
Comment 7 Hubert Verstraete 2005-09-12 08:33:21 UTC 
I've tested with kernel 2.6.13-git11 with SMP feature. It works, but of course
there are less entries in /proc/acpi compared to my current kernel
2.6.12-1.1398_FC4smp (alarm, sleep, ...).
