Warning Hardy Early Adopters
I have been using 64-bit Ubuntu Hardy Heron pre-release on my new work laptop, a Dell Latitude D830. There have been a few glitches, and there are still a few bugs affecting the laptop, but it is usable. The two most annoying issues left are: CPU stuck on high speed coming from suspend, and wireless slow to reconnect after suspend (sometimes manual reconnect needed).
Today I noticed Firefox updates available, and decided to install. I’ve never had any dataloss issues with Firefox, and in fact the last time any Mozilla product lost my data was probably around Netscape 6 time. But now, after the installation of all the updates, and rebooting like it asked, my whole profile was gone. No bookmarks, no remembered passwords, no history, nothing. And of course I had not made backups, because I was thinking I will redo my setup once Hardy Heron is officially released. But after losing the complete profile I did realize I ended up losing some valuable bookmarks I may not be able to remember, even though I have just used the laptop a little while.
So, if you are using Hardy Heron and see a Firefox update, I recommend you back up your profile before proceeding.

Hello,
Does your CPU run hot too? Any idea on how to fix? I have a D830 too running Hardy. Worked fine before the upgrade.
Thanks,

I haven’t measured the CPU temp, but the fan does not seem to be on more than I would expect. There are several bugs on Launchpad that could be this issue, and in one at least people had measured power usage before and after suspend, noticing power usage was up after suspend.
The workaround for some people has been to unload acpi_cpufreq module before suspend, and load it back when coming back from suspend. The trouble is, it seems like you need to compile a custom kernel to be able to do this. See https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/183033
I should also note that my hard drive is suffering from the frequent load/unload cycle which can kill the drive faster than normal. There are workarounds, but that does not seem to work for me all the time. See https://bugs.launchpad.net/ubuntu/+source/acpi-support/+bug/59695
