@Miroslav, It may be one of several issues. So if you are willing, we can tease these out with some sanity checks. I've just read an ASPM document from http://msdn.microsoft.com/en-us/windows/hardware/gg462958.aspx and it states:
"If the BIOS indicates that the platform does not properly support ASPM, the operating system disables ASPM. This can be conveyed in the ACPI fixed ACPI description table (FADT) table IAPC_BOOT_ARCH flags by setting the PCIe ASPM Controls bit to 1." To sanity check this, can you send me a copy of your ACPI tables using: sudo acpidump > acpidump.txt ..and I will see what the IAPC_BOOT_ARCH flag is configured to. Incidentally, the BIOS default basically refers to how the firmware configured the PCI config regions for your PCI-e devices - it may be that theses are mis-configured and causes the wifi card to misbehave when the kernel tries to go into a power saving state and the H/W does not support it correctly. It's hard to tell w/o some further investigation. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/656745 Title: notebook always crashes if on battery (dell vostro 3700 and others) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
