+++ This bug was initially created as a clone of Bug #384881 +++ -- Additional comment from tburke on 2007-11-12 14:17 EST -- Jeff suggests this is still an issue: <jburke> 2.6.21-38.el5rt panics <jburke> http://rhts.lab.boston.redhat.com/cgi-bin/rhts/test_log.cgi?id=696616 -- Additional comment from tburke on 2007-11-12 14:18 EST -- Hanging on an HP xw9300 Viper. -- Additional comment from mschmidt on 2007-11-15 09:41 EST -- Jeff's report shows a different bug. It's not related to sata_nv. The kernel can't find the root filesystem, which is on an LVM volume on LSI MPT Fusion. Notably missing from the RT kernel output is the mptbase driver's message "mptbase: Initiating ioc0 bringup". Neither 2.6.21-50.el5rtvanilla works. -- Additional comment from mschmidt on 2007-11-15 10:58 EST -- I tried these Fedora kernels on hp-xw9300-01: kernel-2.6.21-1.3194.fc7 kernel-2.6.23.1-21.fc7 kernel-2.6.23.1-42.fc8 They all crash in the same way. mptbase does not find the disk. -- Additional comment from mschmidt on 2007-11-16 09:27 EST -- The modules mptbase, mptscsih and mptspi are loaded by initrd, but mptspi's PCI .probe() method does not get called on 2.6.21-50.el5rt. -- Additional comment from mschmidt on 2007-11-21 10:15 EST -- I bisected through RHEL5 kernels to find the magic which makes it work: 2.6.18-1.2717.el5 does not work. 2.6.18-1.2720.el5 works. 2720 includes a fix for bug 207396. Basically it blacklists HP xw9300 and xw9400 and disables MMCONF and PCI segments. ----- hp-xw9300-01.rhts.boston.redhat.com does not boot with Fedora kernels. RHEL5 works because it has a fix for bug 207396. This fix is apparently missing from Fedora (and presumably upstream too).
mmconfig is off by default in F8
2.6.23.1-49.fc8 does not boot on hp-xw9300-01.rhts.boston.redhat.com. If mmconfig is off in F8, it must be the other thing from bug 207396: pci_noseg From 2.6.23.1-49.fc8's boot: ACPI: bus type pci registered PCI: Using configuration type 1 ACPI: Interpreter enabled ACPI: (supports S0 S1 S3 S4 S5) ACPI: Using IOAPIC for interrupt routing ACPI: PCI Root Bridge [PCI0] (0000:00) PCI: Transparent bridge - 0000:00:09.0 ACPI: PCI Root Bridge [PCI1] (0001:40) PCI: Multiple domains not supported ACPI: Bus 0001:40 not present in PCI namespace ACPI: PCI Root Bridge [PCI2] (0002:80) PCI: Multiple domains not supported ACPI: Bus 0002:80 not present in PCI namespace

Created attachment 269781 [details] hack: PCI domains 2.6.23.9 (and I assume F8's kernel too) can be made to work with this (hacky and incomplete, not for merging) patch backported from 2.6.24-rc2. Only works on x86_64 and it does not respect pci=nodomains.
Created attachment 269891 [details] patch for F8 This is a backport of two commits: 32a2eea795643929a43cbbba00d8c4a176b309bf PCI: Add 'nodomains' boot option, and pci_domains_supported global * Introduce pci_domains_supported global, hardcoded to zero if !CONFIG_PCI_DOMAINS. * Introduce 'nodomains' boot option, which clears pci_domains_supported on platforms that enable it by default (x86, x86-64, and others when they are converted to use this). a79e4198d1effbba040e9bf407a95fc9b3418789 PCI: X86: Introduce and enable PCI domain support * fix bug in pci_read() and pci_write() which prevented PCI domain support from working (hardcoded domain 0). * unconditionally enable CONFIG_PCI_DOMAINS * implement pci_domain_nr() and pci_proc_domain(), as required of all arches when CONFIG_PCI_DOMAINS is enabled. * store domain in struct pci_sysdata, as assigned by ACPI * support "pci=nodomains" Applies to kernel-2.6.23.8-63.fc8.
Dave, You can either apply the above patch to F8's kernel, or just CLOSE this as RAWHIDE.
Looks like RAWHIDE then...
