[Bug 58386] Re: ACPI: Looking for DSDT ... not found! (message during boot)
The problem here is that the message is not clear enough. It looks like an error message, but it is not. In fact, nearly every Ubuntu system logs this message on every boot. It simply means that there is no DSDT override included in the initramfs, and it should say that instead. This should be a one-line patch. I suggest: ACPI: Checking for DSDT override...

[Bug 58386] Re: ACPI: Looking for DSDT ... not found! (message during boot)
The purpose of this optional kernel feature, enabled by CONFIG_ACPI_CUSTOM_DSDT_INITRD=y in the kernel .config at build-time, is to allow the user to replace the BIOS Advanced Configuration Power Interface (ACPI) Differentiated System Description Table (DSDT) with one that has been modified to solve problems in the BIOS shipped by manufacturers. The message you see is correct. As far as the kernel is concerned it is an error because it is told to expect to find a replacement DSDT.aml and it isn't there. However the message could be altered somewhat to make it sound less harsh. Once a modified DSDT has been built using the Intel iasl tool it is copied to /etc/initramfs-tools/DSDT.aml and the initrd image rebuilt: $ sudo dpkg-reconfigure linux-image-$(uname -r) This installs the DSDT to /DSDT.aml in the initrd image. The functionality (and messages you see) is implemented in drivers/acpi/osl.c::acpi_find_dsdt_initrd(void) For more information, see: https://help.ubuntu.com/community/ACPIBattery -- ACPI: Looking for DSDT ... not found!

[Bug 58386] Re: ACPI: Looking for DSDT ... not found! (message during boot)
Re-opening (I think). Even if this is not a real error (ie, if not having a DSDT is a normal situation), this is still a user-interface bug: it should not be reported as a boot-time error. The message should be changed to something more descriptive, like file /DSDT.aml not found, using defaults or whatever is appropriate. I couldn't find any recent docs on this, what is it supposed to do, anyway? I'm always having issues with ACPI and I'm always on the look for hacks. Is there anything I can do (ie, compile a file) and perhaps include it in a package to help support my laptop type better (Dell Latitude D620). I'm attaching 2.6.22 too, as I still get this message on Gutsy with the newest kernel. ** Also affects: linux-source-2.6.22 (Ubuntu) Importance: Undecided Status: New ** Changed in: linux-source-2.6.15 (Ubuntu) Status: Invalid = New -- ACPI: Looking for DSDT ... not found!

This is not a definite fix, but rather a workaround. Try disabling ACPI altogether. There's a nice forum thread on the topic: http://ubuntuforums.org/showthread.php?t=2620 Another thing to try is to dig around in your motherboard's BIOS, since most motherboards nowadays have Linux listed as one of the choices under Installed OS. Also check the motherboard manufacturer's website to see if there is a BIOS upgrade available for your motherboard.

My bios only has a switch for the OS type: OS2/Non-OS2 -- I set it to Non-OS2. I'll give the disabling ACPI thing a shot, though actually I DO want to use it. The kernel bug team confirmed that the problem is ubuntu's initrd since the message can't be found in any kernel source.

Dear Jeremie, Since you were listed as the uploader of initrd-tools, I'm hoping you can help. I'd like to figure out two things: 1. Was the package initrd-tools imported directly from Debian? 2. As indicated in the Linux kernel bug report ( http://bugzilla.kernel.org/show_bug.cgi?id=7089#c6 ), this is most likely an issue with this package. As such, should this be referred to Debian bugzilla or was this a locally (Ubuntu-only) change?

[Bug 58386] Re: ACPI: Looking for DSDT ... not found! (message during boot)
System: IBM T22, Ubuntu Edgy, 256MB RAM Using Edgy, when I boot my system I get far more frequent fsck checks than I ever used to on Dapperit seems to do it nearly every boot, not every 30 or so mounts as it used to. Anyway, after the fsck check I get an error stating: ACPI: Fatal Opcode Executed It has a bunch of number that precede the error, for example: [009087763:977683] ACPI: Fatal Opcode Executed. These numbers aren't the exact example (I just made them up). It is hard to log down the actual numbers during boot because it passes quickly once the error appears and edgy boots into X. Can anyone tell me what this problem is? Is it serious, as in Fatal!? Is there a solution?

I like to add that this message still appears in the 2.6.17-10-generic (amd64 or x86_64) kernel in Edgy Beta. Yet, earlier in the boot messages it appears that ACPI: DSDT ... is indeed found and used. The file /proc/acpi/dsdt is indeed present, and not empty. As a matter of interest, I also use a 2.6.17 (amd64) kernel on a Gentoo box, here the offending message is absent. So, it would indeed appear the result of some Ubuntu patch. -- ACPI: Looking for DSDT ... not found!
