Intelfbdrm slows boot?
 

Good Day,

I have a Toshiba ND-205 netbook with the Intel 945GME video card. The machine worked just fine in Slackware 13.0 except for the intel sound. Slackware 13.1 has solved this issue but I have a new one. I takes 4 minutes to boot from LILO to the KDM login manager and it was much faster under 13.0. I have noticed, don't ask how, that the machine boot faster if I hold down the “shift” key during the boot process. Careful timing reveal a boot time of 1:30 from LILO to KDM as long as I dutifully press and hold the shift key down. I believe the slowdown begins when the display shifts to using the inteldrmfd driver. Normally I avoid this problem by using disk hibernation and this helps but the machine is slow to hibernate unless I press and hold the shift key. Any thoughts?

I have included any lines in demsg that mention intel below:

intel_rng: FWH not detected
agpgart-intel 0000:00:00.0: Intel 945GME Chipset
agpgart-intel 0000:00:00.0: detected 7932K stolen memory
agpgart-intel 0000:00:00.0: AGP aperture is 256M @ 0xd0000000
fb0: inteldrmfb frame buffer device
hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj.

I suspect that this is an interrupt related issue. By holding down the shift key you are generating interrupts.
There was a recent thread where the line
was reported. Try the fixes suggested there.

Fixed!
 

I used the "pci=nomsi" boot option and it works fine now.
