[Bug 67110] Re: Kernel instabilty on Medion MD41300 with Hyperthreading enabled / Mobile Pentium 4 HT 3.06Ghz

[Jef]

I still use this notebook and reinstalled Lucid, coming from Hardy. I
once used to test an in between version with a live cd after enabling
hyperthreading in the bios and I let it run the whole night. In the
morning there wasn't a freeze, so I assumed it  was fixed. After the
installation of Lucid, when I was copying back my homedir, I had my
first freeze again. So now I just disabled hyperthreading again. I'm
going to try some tips from above again to see if they work now if I
don't have any other problems anymore.

One of the other problems is that I had a couple of times the same kind
of freeze when installing software using the Ubuntu Software Centre,
when HT is disabled! No problems with apt-get. Never had it in Hardy
when HT was disabled.

When booting, I have to press enter a couple of times, or otherwise the
screen stays the same (black with blinking _ or the ubuntu splash
screen). Same thing with shutting down. However, both have succeeded
without pressing any key, but most of the time I must press a key a
couple of times and then it continues to start up or shut down. Today I
waited an hour and then it even wouldn't start up. I had to press the
power key.

I tried Mint first, but I had more problems there. Everything wasn't
snappy anymore. E.g. the turning cube was still fast, but for me it
seems it had missing frames. Ubuntu works fine, but when playing a video
file now, it is missing frames. It has been fine after install, but now
it isn't.

In short: the bug is still there but there are more compared to Hardy.
