ia64_log_get error while booting

I'm new to Linux on the IA64. I installed Redhat 7.2 for the Itanium on a Lion system this morning. It seemed to work fine. I changed my screen resolution and rebooted. I get a warning saying that my event log is full. Linux starts to boot, but then it goes into what seems to be an infinite loop of alternating error messages. They go by very quickly, but I believe that they are:
ia64_log_get: Failed to retrieve SAL error record type ...
ia64_mca_cpe_int_handler: received interrupt. vector =
I've looked in the kernel source and both messages come from mca.c. I'm not sure what the problem is. I can't boot the machine, not even from the Redhat CDs.

Daniel,

What BIOS are you running on your Lion? Older BIOSes did not have the correct firmware support for machine checks, so if you boot a kernel with CONFIG_IA64_MCA enabled in the kernel config, this behavior could result.

You have two options:

1. Upgrade your BIOS - this is only an option if you have an OEM Lion (it is not recommended or supported by Intel to upgrade the BIOS past build 83 on SDV Lions). You can determine if you have an OEM Lion by looking at the back of the legacy I/O card inside the machine - OEM machines will have "OEM Legacy" silkscreened on the back of the card.
2. Disable CONFIG_IA64_MCA in your .config file, rebuild the kernel, then reboot with that new kernel.

Jenna

Well, it works now. All I did was power cycle the machine. I have no idea what could have been wrong. I'll have to take a look at the BIOS level next week.

Thanks for the help.

I've been tracking this problem on my machine. I've worked out that if I have a CD in the drive with the drive door closed when the machine is powered on it will boot and run. If there isn't a CD in the drive and the drive door is closed when I boot the machine the kerenl hangs in the MCA code.

I'm running Redhat 7.2 with a bios 109.
