I just rebooted one of my SAN hosts, running FC6, and had it boot into the latest FC6 kernel 2.6.22-9. After the boot, the primary SAN partitions it mounts weren't available. A check through /var/log/messages revealed this little nugget:
Nov 9 10:01:04 blowingrock kernel: QLogic Fibre Channel HBA Driver Nov 9 10:01:04 blowingrock kernel: e1000: eth0: e1000_probe: Intel(R) PRO/1000 Network Connection Nov 9 10:01:04 blowingrock kernel: ACPI: PCI Interrupt 0000:01:01.0[A] -> GSI 28 (level, low) -> IRQ 28 Nov 9 10:01:04 blowingrock kernel: qla2xxx 0000:01:01.0: Found an ISP2300, irq 28, iobase 0xffffc20001438000 Nov 9 10:01:04 blowingrock kernel: qla2xxx 0000:01:01.0: Configuring PCI space...

So, in my panic, I reset grub to point back to the existing .20 kernel and all came up just fine:

So my question, WTH is going on here? I've obviously missed a memo or something.
