Description Anantha Subramanyam 2008-03-26 21:13:33 EDT
Description of problem:
Following piece of code in quirks.c of RHEL4.6 code is disabling msi on all
HT1000 systems. This section of code has subsequently been refined in the later
kernels and those changes needs to be pulled into future releases.

/* The Serverworks PCI-X chipset does not support MSI. We cannot easily rely
 * on setting PCI_BUS_FLAGS_NO_MSI in its bus flags because there are actually
 * some other busses controlled by the chipset even if Linux is not aware of it.
 * Instead of setting the flag on all busses in the machine, simply disable MSI
 * globally.
static void __init quirk_svw_msi(struct pci_dev *dev)
	pci_msi_quirk = 1;
	printk(KERN_WARNING "PCI: MSI quirk detected. pci_msi_quirk set.\n");

Installed RHEL4.7-Snapshot1 on a HT1000 system. Used a Gigabit network card and
confirmed that MSI is now working on HT1000 systems.
