Hi,

I tried three more kernels.

2.6.25-rc5
2.6.23.17
and
2.6.23.11

and I get the same result with all three of them which is puzzling for me,=
=20
because once 2.6.23.11 was ok and first came the timeouts then the timeouts=
=20
and then the hardware changes (PATA harddisk replaced with SATA harddisk).

this is with 2.6.25-rc5 on a coldboot:

complete dmesgs are attached. Please ignore the kernel names. After=20
doing 'make oldconfig' I forgot to remove the 'reiser4_ahci_debug' part. Al=
l=20
three kernels are built from unpatched sources.
All I did was copying the config of 2.6.24 and doing make oldconfig.

If  there is something I could/should try/do please tell me so.
