Kernel unaligned access : daily-build 20070221 / kernel 2.6.18-4 / sparc netra X1

[filib <filib@laposte.net>]

hi all,

On  sparc/netraX1, i had a lot of success with previous debian-installer
 (based on kernel-2.6.17)

But now, i'm trying the latest debian-installer  based on kernel
2.6.18-4, and i have the following problem.

As described in all mailing list, during the install, i need to unload
dmfe module, and load manually the correct tulip network module.

The module is loaded correctly, i can launch dhlient.
and just after this action, i see the following message:

It's not an openprom version, because this problem occurs with old and
lates openprom version.

Did you have any idea or hints?
