hello im also having problem now with nmay BT3f sdhc install.
before i dont have this problem only after i installed kdebluetooth.
the problem is confined only on my "persistent changes" option

i have made a persistent changes on my sdhc
if i boot with the option "changes=/dev/sda5" i get the blackscreen after the bootsplash
but then if i edit out that "changes=/dev/sda5" i go straight to desktop..

what could be wrong with my "/dev/sda5"? what can i do to correct this. this just happend now
