does the problem still exist in the latest upstream kernel, say 2.6.35 or 2.6.36-rc?
Please post acpidump for the machine.
Created attachment 36832 [details] acpidump output Added acpidump output as attachment
Could you please try latest kernel 2.6.36? The ACPI errors should be fixed already.

Added latest logs and ACPI tables dump from the logs. I'm using A01 version of the Dell Vostro V13 BIOS, if this can help
