Re: [CentOS] Issues installing x86_64 5.1 on Ultra 40

Try booting while disabling ACPI and APIC.

linux noapic noacpi

at the boot menu.

We'll give that a try.

In addition, error message output:

An error occurred trying to format VolGroup00/LogVol00. This problem is serious, and the install cannot continue.

Press <Enter> to reboot your system.

dmesg output <6>sd 0:0:0:0 SCSI error: return code = 0x00040000 <4>end_request: I/0 error, dev sda, sector 504029 <4>printk: 646939 messages suppressed. <3>Buffer I/) error on device dm-0, logical block 19596153 <4>lost page write due to I/O error on dm-0

Again, it sure looks like a hardware problem, but using x86 Solaris 10 on the same disk works perfectly.
