I have a SGI O200 (dual 250MHz CPUs, 1GB RAM) with three PCI cards installed in the main chassis card cage (i.e., Slot 1: Ethernet controller: Silicon Graphics, Inc. AceNIC Gigabit Ethernet (rev 01); Slot 2: SCSI storage controller: QLogic Corp. QLA2200 64-bit Fibre Channel Adapter (rev 05); and Slot 3: SCSI storage controller: QLogic Corp. ISP1080 SCSI Host Adapter (rev 01). These cards worked fine when the machine ran IRIX. A new build of gentoo-mips-2.6.20.18 with gcc/kgcc-4.1.1 is stable, except that the three PCI mentioned above are not initialized during boot-up. The relevant 'dmesg | grep PCI' messages are: myhost ~ # dmesg | grep PCI PCI: Device 0000:00:05.0 not available because of resource collisions qla1280: QLA1040 found on PCI bus 0, dev 0 PCI: Enabling device 0000:00:00.0 (0006 -> 0007) scsi0 : QLogic QLA1040 PCI to SCSI Host Adapter qla1280: QLA1040 found on PCI bus 0, dev 1 PCI: Enabling device 0000:00:01.0 (0006 -> 0007) scsi1 : QLogic QLA1040 PCI to SCSI Host Adapter qla1280: QLA1080 found on PCI bus 0, dev 7 PCI: Device 0000:00:07.0 not available because of resource collisions PCI: Device 0000:00:06.0 not available because of resource collisions myhost ~ # From dmesg, it is apparent that there are "resource collisions" for each of the three PCI cards (i.e., devices 05, 06, and 07 on bus 00). Further, a 'lspci -vv' shows that each of the three PCI cards do not have proper IRQs assigned; that is, each card has "Interrupt: pin A routed to IRQ 0", as shown below: 00:05.0 Ethernet controller: Silicon Graphics, Inc.

Finally, I rebuilt the kernel with the IOC4 framework installed, but there was no change in the symptoms of this problem. Thus, I'm stuck. The PCI cards appear to be recognized by the kernel, but not properly initialized. Please help.

Created attachment 179835 [details] gentoo-mips-2.6.20.18 .config file This attached file is the .config used to build the gentoo-mips-2.6.20.18 kernel affected by the reported PCI slot initialization problem.
This is Gentoo Linux on mips hardware. yes? The alt team doesn't do that...please review how you are creating bugs, this is not the first time I have seen a misassigned bug from you. (If you are unsure of where to file it, please let the bug-wranglers do it) Thanks.
Thanks. And apologizes for creating some extra work for you. I did not see an assignment option related to mips on the bug submission form. I'll figure out who the bug-wranglers are and, then, send my future issues through them. I thought this was a public forum for reporting problems, based on the installation docs provided with gentoo.
you can just leave the "assign to" field blank when filing your bug and it will be handled by the bug wranglers.
Is this still a bug? 2.6.20 is pretty ancient. Since many reporters seem to ignore old bugs like this, I'm going to close this one, but please reopen if it's still a bug with newer kernels. Even then, I think this is a bug for upstream.
