Whoa, there is something wacky going on with my git tree I think. Obviously from the git log output I pasted it looks like the patch is already applied to Hardy, but further examining the actual file(s) I'm not seeing the patch applied. I even re-cloned my git tree (git clone git://kernel.ubuntu.com/ubuntu/ubuntu-hardy.git) and see the same odditiy. So please disregard my comment that this is already in Hardy. -- BUG: soft lockup - CPU#0 stuck for 61s! https://bugs.launchpad.net/bugs/214814 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi TJ, The patch you referenced in an eariler comment ( https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/214814/comments/3 ) seems to already be in both Hardy Heron 8.04 and the upcoming Intepid Ibex 8.10 kernel already.

A simpler fix was provided by Matthew Wilcox on linux-pci mailing list. It is cleaner and simpler than my DMI-based patches. Matthew's suggested patch then came to the attention of Zhao Yakui on linux-acpi who reported a patch is already in the -mm tree that solves a similar report at buzilla: "Intel SC450NX system stops working with kernels later than 2.6.22.x" http://bugzilla.kernel.org/show_bug.cgi?id=10124 That patch has been tested and confirmed working.

The issue is caused because this chipset has 3 PCI root buses. When it was first released some operating systems (read: Windows NT) didn't always correctly discover the 2nd and 3rd PCI buses. As a result the PCI BIOS tables were 'hacked' to have a fake bridge device on PCI bus 0 that points to the same bus number as the 1st bus so they would be scanned correctly by the OS. $ lspci 00:0a.0 PCI bridge: Intel Corporation 21154 PCI-to-PCI Bridge 00:10.0 Host bridge: Intel Corporation 450NX - 82451NX Memory & I/O Controller (rev 03) 00:12.0 Host bridge: Intel Corporation 450NX - 82454NX/84460GX PCI Expander Bridge (rev 04) 00:13.0 Host bridge: Intel Corporation 450NX - 82454NX/84460GX PCI Expander Bridge (rev 04) 00:14.0 Host bridge: Intel Corporation 450NX - 82454NX/84460GX PCI Expander Bridge (rev 04) As a result, in a well-behaved OS the 2nd and 3rd PCI buses would be scanned twice. Once as secondaries of the 1st bus, and then as root buses in their own right. This caused problems with devices being discovered twice. A fix-up for all i450N chipsets was introduced in arch/i386/pci/fixups.c::pci_fixup_i450nx(). Note: arch/i386 was refactored to arch/x86/ subsequently. The fix-up checks the PCI config for the subsidiary buses and if it finds them scans them. This adds them to the root_pci_bus list. Later in the boot process the ACPI/PCI code reads the ACPI DSDT table, finds the PCI bus entries (PNP0A03) and tries to scan them. It fails when scanning the 2nd and 3rd buses with: [0.910906] ACPI: PCI Root Bridge [PX0B] (:02) [0.912085] ACPI: Bus :02 not present in PCI namespace [0.917111] ACPI: PCI Root Bridge [PX1A] (:03) [0.920085] ACPI: Bus :03 not present in PCI namespace Unfortunately, the report is misleading since the reason is that the bus is found to be already registered and therefore ignored. The situation can be worked around by booting with "pci=noacpi". The solution is to make the pci_fixup_i450nx() code selected based on the DMI of the system. I've introduced a patch that does this. Initially the only DMI it will match is Dell PowerEdge 6300 but if other systems are found to be affected the output of "sudo dmidecode" should be captured and reported. Additional DMI_MATCH entries can then be added to the patch. I found this reference to the issue in AKM's 2.6.0 mm tree and the linux-scsi mailing list archive: "I can tell you what's going on here. This is a 450NX based motherboard. The 450NX chipset from Intel was the first chipset to have peer PCI busses. For backwards compatibility, some machine makers hacked their PCI BIOS to have a fake bridge device on PCI bus 0 that points to the same bus number as the peer bus. This way if the OS didn't know about the peer bus registers it would still find the devices by scanning behind the bridge. In this case we are scanning behind this fake bridge and then also scanning based upon the peer bus registers in the chipset, and as a result we are finding the device twice. In order to fix this problem you need to change the peer bus quirk code for the 450NX chipset to scan the list of bus 0 devices looking for a bridge that has the same config as the peer bus registers and if so delete the bridge from the list. That will avoid double scanning and will avoid having the PCI code try and configure sub busses via a fake bridge when it should do all configurations via the 450NX peer bus registers. -- Doug Ledford <[EMAIL PROTECTED]>" http://marc.info/?l=linux-scsi&m=106839680416899&w=2 In this particular case a Dell PowerEdge 6300 with a PERC 2 RAID array - controller (aacraid) fails to boot on any kernel after v.2.6.20 - (Feisty).
