normally PCI bus order determines the "within the same driver" order. PCI bus order comes from the firmware (eg bios), so if you switch from/to acpi or upgrade your bios this might change. Still using mount-by-label is strongly recommended Created attachment 102510 [details]
SCSI initialisation
Relevant SCSI details from dmesg, whole can be supplied if required.
I've verified and regenerated the initrd for both kernels from identical modprobe.conf. BIOS was not altered between boots, ACPI is active on both, stock kernel arguments (ro root=LABEL=/) - can reproduce that 2.6.6-x gives one ordering, 2.6.7-x gives an alternative ordering. There is a difference in reported IRQ - chipset is a ServerWorks CSB6. mount-by-label obviously does not work for swap partitions, the alternative, devlabel, is only initialized after swap activation? I'm unsure if the device change affects LVM physical volume groups. can you attach lspci -vx from both kernels ? are you sure you're not upgrading from an smp to a UP or vice versa kernel ? Created attachment 102511 [details]
lspci -vx (2.6.6-1.435.2.3smp)
Created attachment 102512 [details]
lspci -vx (2.6.7-1.494.2.2smp)
Yes, sure - both are smp, not booting into UP kernel. Fedora Core 2 has now reached end of life, and no further updates will be provided by Red Hat. The Fedora legacy project will be producing further kernel updates for security problems only. If this bug has not been fixed in the latest Fedora Core 2 update kernel, please try to reproduce it under Fedora Core 3, and reopen if necessary, changing the product version accordingly. Thank you. |
