Subject: Re: 2.6.39-rc5-git2 boot crashs

Enclosed the config and compilation log file (with some 
warnings, things which should be corrected also). Perhaps 
it's useful for find the error.

Right now my computer crashed again when I unzipped a big 
file.  As said in the 2.6.39-rc1 until -rc4 reclamations, 
 the computer always crashs if zip, unzip or move big 
files.  This looks like an error of the memory / paging 
driver.

w.r.t. my last message, it should be ata1 rather than ata0 
.  ( See, enclosed a foto of such reboot-resistent 
secondary crashs (happened after a big primary crash) on 
which 'anything' was interpreted as ata )
