Comment 201 for bug 524281

Yuppie, now it "seems" again that I have found the good combination:

- Nothing fixes the cpu frequency flickering. The laptop just shits on the cpufreq settings and decides on its own, what is the best frequency for me. Come on... Sucks.
- This "Load balancing tick" bullshit stopped when I downgraded my bios back to the original version what the laptop had when it was shipped. I upgraded recently to the newest version and it was my last idea like the root cause of these problems. Laptop: Dell Latitude E4300, the BIOS version A06 again.
- But I got back an old bug with v2.6.39-rc4-natty kernel. Namely the backlit of the LCD did not come back after resume. Nice. I switched back to the original natty kernel and this problem seems to be solved also.

So the "workaround recipe" for Dell Latitude E4300 owners with this bug:

1. Downgrade the BIOS to an earlier version. A06 or A07 is a good candidate. (I googled a manual to make a pendrive with bootable DOS and I downloaded the A06 BIOS "upgrade" file from the Dell site to the pendrive.)
2. If this bug still happens -> upgrade to Natty.

Other notes:
(3a. In any way, disable the bluetooth in the BIOS. It just makes problems with suspend/resume and for me, an attempt to send file via bluetooth from my phone made the laptop frozen with a kernel oops.)
(3b. I do not think so that it makes anything better, but I have installed the latest Intel graphics drivers from the mentioned PPA in my previous comments.)

Uff.
