Did booting w/ ACPI ever work properly on this hardware with any version of the kernel -- or as far as you know this has always been broken? Always broken, so far as I can tell. This is a very new box, but what I have tried (without success with acpi=on): 2.6.14-rc5 2.6.14 2.6.14.4 2.6.15-rc6 If there's a particular revision you'd like me to try, I can do that. Cannot build kernels earlier than 2.6.12: tried 2.6.10, 2.6.11, 2.6.11.12. Could build: 2.6.12 2.6.13 but they have the same problem. Or at least they still don't see the second video card with acpi on (I didn't try them with acpi=off). >ACPI: PCI Root Bridge [PCI1] (0001:40)

As far as I can tell, Linux x86/x86-64 doesn't support multiple domains
currently. This might cause some buses can't be scanned in your box.
Curious that in "acpi=off" mode the 'lost' devices appear in domain 0000: 0000:61:06.0 SCSI storage controller: LSI Logic / Symbios Logic 53c1030 PCI-X Fusion-MPT Dual Ultra320 SCSI (rev 07) 0000:61:06.1 SCSI storage controller: LSI Logic / Symbios Logic 53c1030 PCI-X Fusion-MPT Dual Ultra320 SCSI (rev 07) 0000:81:00.0 VGA compatible controller: nVidia Corporation: Unknown device 009d (rev a1) (prog-if 00 [VGA]) What do you see if you boot with "pci=noacpi"? Whoops. I left the job where I had access to this machine about a month ago. |
