Description Wouter de Jong 2006-07-20 06:20:08 UTC

Most recent kernel where this bug did not occur: 2.6.16.20
Distribution: Custom distribution based on RedHat 6.2 (glibc2.3 though)
Hardware Environment: SuperMicro SuperServer 6013L-8 Intel dual Xeon with 
HyperThreading
Problem Description: Since 2.6.17(.-1 t/m .6) booting fails on a SuperMicro 
SuperServer 6013L-8, with dual Intel Xeon with HyperThreading.

The machine fails during booting right after the message 'PCI: Probing PCI 
hardware'

This did NOT happen with 2.6.16.20 and lower.
It also happens with 2.6.18, 2.6.18-rc2, 2.6.18-rc1-mm2
It does NOT happen with 2.6.18-rc1-mm2 when SMP is NOT compiled in the kernel. 
Booting with nosmp still triggers the problem though.

I've managed to track down where the problem occurs, and it's on 
drivers/pci/probe.c -> function pci_scan_bus_parented()
And then specifically, this line :

b->subordinate = pci_scan_child_bus(b);

When I modify this in 'b->subordinate = 2;' ... the Oops does not occur.
But then it will crash due to not found harddisk devices (SCSI @ Adaptec 
dpt_i2o), which probably is the result of the static '2'.

I have various boot messages with Oopses available, I'll attach a few of them.



Steps to reproduce:

Boot a system like this with a 2.6.17/2.6.18 kernel, and it will crash when 
pci_scan_child_bus() is called within function pci_scan_bus_parented()

Comment 5 Wouter de Jong 2006-08-08 04:46:16 UTC

Seems fixed in 2.6.18-rc3-mm2, but NOT in 2.6.18-rc4

Comment 6 Daniel Ritz 2006-08-16 05:27:35 UTC

it seems your BIOS is somewhat broken. 2.6.17 changed the ordering in which
PCI access methods are probed. so with kernel <= 2.6.16 it would use direct access
but with 2.6.17+ it would use the BIOS routines. 2.6.18-rc3-mm2 has a (broken)
patch to address the problem. the correct one will show up in next -mm, but i
attach it anyway here. you can try it on top of 2.6.18-rc4. should fix it.

Created attachment 8798 [details]
pci init: PCBIOS as last fallback

Comment 8 Wouter de Jong 2006-08-16 07:17:05 UTC

Perfectly fixed, also checked with 2.6.17.8 :)

Many thanks!
