The suggested kernel patch pointed to by kurt (http://lkml.org/lkml/2007/5/8/510) was added to the mainline kernel in 2.6.22.2 and is in Gutsy.
Therefore if this issue is still occurring on Gutsy Tribe-5 we need to look more closely. Please attach the DSDT of the system using:
$ sudo apt-get install acpidump $ sudo acpidump -b -t DSDT -o MODEL-BIOSVERSION.aml $ tar -cjvf MODEL-BIOSVERSION.aml.tar.bz2 MODEL-BIOSVERSION.aml
replacing MODEL and BIOSVERSION with your PCs specific values.
