Subjectnforce2 unknown memory device
Date
hi

linux is not able to detect all the memory installed on my mainboard.
my kernel is 2.4.22 but i tried 2.4.23pre2, 2.6.0-test3-6[mm3].
i tried with 4gb and without.

lspci schows:
00:00.0 Host bridge: nVidia Corporation: Unknown device 01e0 (rev c1)
00:00.1 RAM memory: nVidia Corporation: Unknown device 01eb (rev c1)
00:00.2 RAM memory: nVidia Corporation: Unknown device 01ee (rev c1)
00:00.3 RAM memory: nVidia Corporation: Unknown device 01ed (rev c1)
00:00.4 RAM memory: nVidia Corporation: Unknown device 01ec (rev c1)
00:00.5 RAM memory: nVidia Corporation: Unknown device 01ef (rev c1)
00:01.0 ISA bridge: nVidia Corporation nForce2 ISA Bridge (rev a3)
00:01.1 SMBus: nVidia Corporation nForce2 SMBus (MCP) (rev a2)
00:02.0 USB Controller: nVidia Corporation nForce2 USB Controller (rev a3)
00:02.1 USB Controller: nVidia Corporation nForce2 USB Controller (rev a3)
00:02.2 USB Controller: nVidia Corporation nForce2 USB Controller (rev a3)
00:04.0 Ethernet controller: nVidia Corporation nForce2 Ethernet Controller
(rev a1)
00:06.0 Multimedia audio controller: nVidia Corporation nForce2 AC97 Audio
Controler (MCP) (rev a1)
00:08.0 PCI bridge: nVidia Corporation: Unknown device 006c (rev a3)
00:09.0 IDE interface: nVidia Corporation nForce2 IDE (rev a2)
00:1e.0 PCI bridge: nVidia Corporation nForce2 AGP (rev c1)

i tried to switch the memory sticks but nothing. when i install 1024 MB
ram linux detects 1008; with 512 i get 502.

the xserver can't init agp with the error xf86_ENOMEM; but i think this
is a couse of the missing memory that is not detected.

is that a problem of my hardware (defect) or are the nforce2 chipsets
not yet fully supported?

thanks for your help.
