Comment 13 for bug 183517

Dell OptiPlex 755, Quad Core Q6600, 2.4GHz, 4Gb
Windows XP Pro SP2, fully updated
ATI Radeon HD 2400
Microsoft Virtual PC 2007 6.0.156.0

First time install - not an upgrade - can't run live from CD.

Same problem - "An unrecoverable processor error has occurred", etc. - Attempting install from ubunto-8.04-desktop-i386.iso, downloaded today (5/10/08). Will not run Check CD either. Attempted options noted before - vga=771 - noapic nolapic - nothing works.

This is reproducible. I am continuing testing and will advise if I find anything else.

I previously attempted 7.10 install, but that did not work due to the VPC PS/2 emulation issue.
I thought my problem was a SATA/AHCI issue, but I just spent the afternoon playing with BIOS Legacy Mode to no avail.

Any ideas? Thanks.
