Maybe a kernel bug?

DSDT problem ?

Hi,
I am experiencing the same bug with a Debian and a colleague has the same bug also with the same HP8570w computer with a debian 12.04 (LTS).
I have noticed that the output of *lspci* displays only 1 VGA meanwhile I have an HD4000 chipset with my processor.

I should have needed (and was prepared ) to install bumblebee and primus on such a computer but the INTEL graphics did not show up !
I have tried to look into the DSDT but I lack skills to trace the problem, from what I have read in yhe Hackintosh community problems with HD4000 are common but I have not been able to understand how to modify DSDT to get HD4000 visible and at work...
