Please note that the parameter "
acpi=noirq would be required in order to install the system with Update 3. At the boot prompt, the following would have to be provided:
boot: linux acpi=noirq
If an install is attempted without the above parameter, then the scsi bus resets are seen with the following messages repeated over and over:
mptbase: Initiating ioc0 recovery mptscsi: ioc0: target reset: SUCCESS (sc=f754ec40) mptscsi: ioc0: attempting scsi bus reset! (sc=f754ec40) scsi0: destination target 5, lun 0 command = Inquiry 00 00 00 24 00
acpi=noirq' is needed on Red Hat Enterprise Linux 4 Update 3 because the Update 3 installer kernel operates in PIC mode. This causes the LSI driver on the HS21 to loop infinitely while waiting for the LSI chipset to initialize. Using '
acpi=noirq' works around this problem.
With Update 4, the installer kernel operates in APIC mode by default making '
acpi=noirq' unnecessary with Red Hat Enterprise Linux 4 Update 4.
