Hi all, my laptop (Asus M6R, http://www.fi.muni.cz/~kas/m6r/) has problems with ACPI with newer kernels - most of ACPI operations fail - here is the sample of error messages printed during boot. All other error messages contain the "AE_TIME" line as well:
Initializing Cryptographic API ACPI-0405: *** Error: Handler for [EmbeddedControl] returned AE_TIME ACPI-1138: *** Error: Method execution failed [\_SB_.PCI0.SBRG.EC0_.RDC3] (Node ddf09840), AE_TIME ACPI-1138: *** Error: Method execution failed [\ECIO] (Node ddf09380), AE_TIME ACPI-1138: *** Error: Method execution failed [\_SB_.PCI0.SBRG.EC0_.ACPS] (Node ddf078e0), AE_TIME ACPI-1138: *** Error: Method execution failed [\ACPS] (Node ddf03220), AE_TIME ACPI-1138: *** Error: Method execution failed [\_SB_.PCI0.AC0_._PSR] (Node ddf07160), AE_TIME ACPI-0405: *** Error: Handler for [EmbeddedControl] returned AE_TIME ACPI-1138: *** Error: Method execution failed [\_SB_.PCI0.SBRG.EC0_.SMBR] (Node ddf09540), AE_TIME ACPI-1138: *** Error: Method execution failed [\_SB_.PCI0.SBRG.EC0_.BIF0] (Node ddf07c40), AE_TIME ACPI-1138: *** Error: Method execution failed [\_SB_.PCI0.BAT0._BIF] (Node ddf07e20), AE_TIME I cannot read battery status etc. In 2.6.9 ACPI works, in 2.6.10 (and later) it doesn't. I've tried to do a binary search in order to find an exact change which breaks ACPI for me, and found the following: 2.6.10-rc1-bk11 is OK, 2.6.10-rc1-bk12 is not. So I've diffed the -bk11 and -bk12 trees and tried to trim the patch to an absolute minimum. Now I have a patch (http://bugme.osdl.org/attachment.cgi?id=4534&action=view) which, when applied to 2.6.10-rc1-bk11, breaks ACPI on my laptop, and, when subtracted from 2.6.10-rc1-bk12 (using patch -p1 -R), makes ACPI working in 2.6.10-rc1-bk12. However, the patch does not touch anything related to ACPI (I think). It is a sysfs and kobject update. So I don't see how this can break ACPI for my laptop. It seems the failing methods are always \_SB_.PCI0.SBRG.EC0_.<something>, and they all try to acquire an internal mutex using the following code (from my DSDT): If (LEqual (Acquire (MUEC, 0xFFFF), 0x00)) Do you have any idea on what is wrong here? More information, my source and binary DSDT are attached to the following kernel bugzilla entry: http://bugme.osdl.org/show_bug.cgi?id=4150 Thanks, -Yenya -- | Jan "Yenya" Kasprzak <kas at {fi.muni.cz - work | yenya.net - private}> | | GPG: ID 1024/D3498839 Fingerprint 0D99A7FB206605D7 8B35FCDE05B18A5E | | http://www.fi.muni.cz/~kas/ Czech Linux Homepage: http://www.linux.cz/ | > Whatever the Java applications and desktop dances may lead to, Unix will < > still be pushing the packets around for a quite a while. --Rob Pike < - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
