ACER aspire crash on boot with newer kernels

["Hank J. van Leuvensteijn" <lionstone@mail.com>]

Hello,

I've asked this a week or so ago,  and didn't get much feedback.

If nobody has any ideas about this, maybe somebody knows where else I 
should ask this question?

I have an ACER Aspire with Athlon 64 X2 4800+ processor.

The only flavor I found that will boot this box is Debian with kernel 
2.6.18-amd64

Newer Kernels ALL crash after bringing up the second processor, just 
after a screen message saying:

...
[   0.232014] Brought up 2 CPUs
[   0.232014] Total of 2 processors activated (9988.73 BogoMIPS)
___system freezes___


Any ideas where I can get some help?

Thanks,

Hank
