Hello! I have some IBM HS21-8853 blades, and they work all fine as long as I don't plug in IBM Qlogic QMC4052 iSCSI HBA..
After adding QMC4052 HBA, IRQ routing (?) gets messed up and the USB-based console in IBM bladecenter/chassis (keyboard and mouse) don't work very well anymore.. every keypress gets doubled, and mouse is really wild :) so can't really use the console for anything.. Other devices seem to work fine, ie. it _seems_ to only affect the USB console. Screenshot of what kernel says during system startup: http://pasik.reaktio.net/ibm-hs21-blade-usb-problem-02.jpg irq 74: nobody cared (try booting with the "irqpoll" option) .. Disabling IRQ #74 This problem gets fixed with the suggested "irqpoll" option to the kernel cmdline, ie. console works normally after giving "irqpoll" option to the kernel. Although the "nobody cared" error will still happen during bootup.. I'm running RHEL 5.2 (2.6.18-92) atm. Any ideas how to fix this? I'm running latest IBM BIOS (v1.13) on the Blades.. Is there some option in BIOS that could affect this? Same QMC4052 HBAs work all fine in older IBM HS20-8843 blades.. -- Pasi _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
