Jaunty will not boot on Dell Optiplex 760 unless hpet=disable
|||Dell Ubuntu Project||
MIT is switching its standard recommended desktop configuration from the Dell Optiplex 755 which has
reached end of life to the new Dell Optiplex 760.
Unfortunately there seems to be a nasty kernel bug around HPET.
Boot today's Jaunty Live CD. (I used 3/24/09 and also as another test 1/13/09)
Select your language
Choose "Try Ubuntu..."
Select option ACPI=off
We know from other bug reports for example,
that there is a problem with HPET. That debian bug requests incorporation of a one-line kernel change
that changes an oops message from displaying on every clock tick to one that only appears once.
It does not, however get HPET working.
This problem manifests under Intrepid with much spewage of kernel oops messages and/or terribly slow operation.
Again the work-around of of turning off ACPI seems to help.
The hardware has ICH10 motherboard chips. How new are they?
Also I see a report that the PNP-BIOS is not working, but I do not know if this is relevant.
