Hi Julian, If acpi=noirq seems to solve the problem then it's most probable that your ACPI DSTD is causing the problem. One could look and see if an updated ACPI DSTD is available and either load this at boot time, or see if there is a BIOS upgrade for your machine. A good place to look for updated DSTD's is http://acpi.sourceforge.net/dsdt/view.php?manufacturer=Dell&name=Latitude+D630
There is a discussion of overriding one's DSDT (generic discussion) at : http://www.lesswatts.org/projects/acpi/overridingDSDT.php I'd refer you to https://help.ubuntu.com/community/ACPIBattery for notes on how to compile and load a new DSDT for Ubuntu. Mind you, if acpi=noirq works for you then you don't have to got to the lengths of overriding the DSTD, just edit you grub loader menu /boot/grub/menu.lst (using your favourite editor but sudo'd) to make it a permanent change. Note that it's not necessarily guaranteed that the updated DSTD will solve this particular issue, it just may be worth looking at just in case it solves other issues too.
