Bug Description

Resuming from suspend fails on my Dell x300 laptop. I decompiled and attempted to recompile the ACPI DSDT code and received two warnings.

dsdt.dsl 3610: Field (ECR, DWordAcc, Lock, Preserve)
Error 4074 - ^ Host Operation Region requires ByteAcc access

dsdt.dsl 4463: CreateByteField (BUF0, \_SB.PCI0.LPCB.SIOD.FIR._CRS._Y1E._SIZ, DMA1)
Error 4007 - Field offset is in bits, but a byte offset is required ^

ASL Input: dsdt.dsl - 6210 lines, 232044 bytes, 2597 keywords
Compilation complete. 2 Errors, 0 Warnings, 0 Remarks, 702 Optimizations

The first error was easy to fix. I am hung up on the second.

Even if you all were to know how to fix this, what would you do about it? Does the kernel have the ability to recognize a specific busted dsdt table and replace it with a known good table?

Hi Jerome,

Just curious if there is an updated DSDT that you could use instead that might resolve this? You could try to put quirks into the kernel to try to work around a broken DSDT but it's unlikely that this will happen at this point in time since we are almost at a kernel freeze for Hardy. Have you looked at the following site by chance? http://acpi.sourceforge.net/dsdt/view.php Let us know if it helps. Thanks.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.
