I have been wracking my brain for a week now with a serious problem using the new Ubuntu 8.04, on my brand new JFL92 I got last week. Here is the issue.
When using it, after anywhere from 15 to 60 seconds of idle, the screen freezes. As in cursors that were blinking, stop blinking, and animations that were going, stop going. I move my mouse, and I get 2-3 seconds of huge mouse lag as the pointer jumps from one side of the screen to another, and then things are back to normal.
This happens when I am using wireless, wired, and completely disconnected. I have used various methods to test each scenario and found no coorelation.
It has a repeatable example test. On first boot after a default install, go right to a terminal in gnome and do:
apt-get update
apt-get upgrade
apt-get dist-upgrade
Basically just getting yourself up to date. If you don't move the mouse or press any keys, you will see exactly what I described happen. If you are on wireless, you will at that point have to re-connect to your wireless as it will be in a defunct state. If you are on ethernet, you will resume where you left off, but only after you bring it out of the 'lag'. It will have been recieving no data while in the 'lag'.
This can also be tested by simpling 'ping google.com', after 100 or so replies it will freeze.
Offline this can be seen by just watching 'top' for a few minutes.
Ubuntuforums have not been able to provide me with any help. It is such a HUGE and OBVIOUS issue, and is apparent on first boot with the default install, that I cannot be the only one who is noticing it. My best bet is to find some JFL92 users who can help me out by testing this and seeing if I'm crazy.
JFL92 users who use linux, anyone using Ubuntu and run into this? I am about ready to chuck this JFL92 out the window.
Other notes : Everything works 100% in Vista and XP, I have run 5 memtest86 tests, prime95 on both cores simul, HD tests from OEM and GRC Spinrite, and GPU stress tests; all tests watching temps and volts. This laptop is mechanically perfect.
More notes :
I have bios 116.
noapic doesnt help
apci=no causes kernel panic thrown by a PNP_BIOS error.
I have run the 'Check for errors' and verified the MD5 of my iso, and of the dd of the actual cd when in the cdrom. The burn is perfect.
Similar problems have been reported in the comments of these bugs :
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/217849
https://bugs.launchpad.net/ubuntu/+source/kvm/+bug/217815
But this is not a dupe. I am not using kvm, and in the 20+ times I have installed Hardy, this only happed 2 or 3 times during install. And was always easily put on by just pushing shift. My problem is post install, normal operation.
Again, it is completely repeatable from a default fresh install on the first boot. |
