Comment 14 for bug 574462

Yeah I have this problem too. I have a Eee PC 900 / Linux with the 4G onboard and 16G socketed drives. I'll skip the dmesg since it's identical to others posted with the Eee PC. I would like to note that I first disabled hdparm and it worked as a workaround until I ran update-grub (grub2 on 10.04 UNE). Now in addition to disabling hdparm I have disabled the smart probe and now there are no more 30 second hangs. I'm not sure if they would return if I just enabled hdparm again.. but my guess would be yes. On an earlier installation I reduced the hangs by making sure I set the bios to "start" until I finished the installation then set it to "finished", but I'm not sure if that is related. Before that when I installed with the bios set to finish, it hanged frequently even after boot, but after when I changed the bios the errors would only occur right after getting to the desktop and starting an application. After the initail group of 3 or 4 hangs it would never do it again until reboot. I wonder if grub2 is somehow related to this. Or the padding at the beginning of the partitions. This is all on Ubuntu 10.04 UNE.
