According to HP, http://h18000.www1.hp.com/products/quickspecs/11632_ca/11632_ca.html ---> http://h18000.www1.hp.com/products/quickspecs/11632_di/11632_div.html#Standard%20Features%20-%20Select%20Models the mobo has an 865g chipset. I know of 5 bug reports that confirm using boot parameter - processor.nocst=1 as a workaround for kernels < 2.6.38 linux-image-2.6.39 through linux-image 3.3.0-rc6-686-pae - on both of my 865g based boxes. Also, iirc, the bigmem kernel was swallowed by the 686-pae kernel, which might be a reason for the instability when using 486. > >I've run memtest86+ on this machine and the memory shows no errors in >that program. > >Let me know if there are other details i can report that would help with >this bug report; sorry i'm not able to get the machine to a stable point >yet to run reportbug on it directly. best regards, Will
