SubjectRe: 2.6.39-rc5-git2 boot crashs
At my reclamation thread about 2.6.39-rc3,4 crashs, I 
informed that there was a reset-resistent change of the
system after crashs, so that on subsequent boots (after a
'primary' crash rather at the end of booting) it happened
an early 'secondary' crash at the time of initializing
ata0, with funny effects like that the grafic card (or
anything else) was identified as an ata device, with
subsequent 'read erros' on it and crash. This 'secondary'
effect repeated and repeated and gone away only at booting
with a normal kernel ( or But if
afterwards booting again with 2.6.39-rc3 or -rc4 , then at
the end of the boot it crashed, and at subsequent boots
again continued this reset-resistent effect that it crasha
again and again with ata0 problems, until I reboot with or , or waiting 5 minutes (perhaps until
the memory discharged).

All these problems dont happen with or
