Problem on HP Livestrong L2000 laptop (theoretically identical to Compaq V2000)

[Ning Bao]

Hi! All experts here,


I am using a HP special edition Livestrong L2000 laptop. Theoretically, they
are identical laptop. My laptop is equipped with an AMD Turion 64-bit CPU.

Ok, let me cut in the real issue.

I installed Ubuntu 5.04  (AMD64 64bits system) on my laptop long time ago
and I was working fine. If I am right, the first kernel version I used was
2.6.14-8.  Then, I  kept  my system  updated. Everything was fine until I
upgraded my bios from F.11 to F.13 (F.23 behave the same as F.13). The
situation is that newer kernel (newer than 2.6.14-9) hang up after boot, but
the oldest kernel 2.6.14-8 still works. I tried this many times and I was
seeking for answers, but I got no clue. I was so frustrated and I deleted
Ubuntu from my laptop.

I tried the latest Ubuntu Drapper LiveCD (Ubuntu 66.04 Flight CD4). With
AMD64 LiveCD, F.11 bios works fine, F.23 freezes. I found your ubuntu wiki
page after I met this problem and I noticed you were using X86 system. I
tried it myself. With X86 (32bits) LiveCD, both bios works fine.

Conclusion :There is something wrong when you use a AMD64 system with newer
bios version on a Compaq V2000 (HP L2000) laptop. What's more, this might be
a bug inherited since kernel 2.6.14-9.

Could you please check with Ubuntu AMD64 team to figure out what is going on
here.

Thanks a lot!

Best,

Ning Bao
