</I>><I><BR>
</I>><I>Not being familiar with the gt64260 Ethernet device or<BR>

</I>><I>to<BR>
</I>><I>dev = alloc_etherdev(sizeof (gt_eth_priv_struct ));<BR>
</I>><I>Shortly after, when attempting to allocate the Tx and<BR>

</I>><I>uncachedPages function. I have traced the problem to<BR>
</I>><I>the pmd_presenṭ(*pmd) function in va_to_pte(addr)<BR>
</I>><I>returning 0. I dumped the values of pmd, init_mm, and<BR>
</I>><I>pmd in the va_to_pte() and the values seemed O.K., so<BR>
</I>><I>I commented out the pmd_presenṭ(*pmd) check but was<BR>
</I>><I>once again stopped by the pte_present(*pte) check. I<BR>
</I>><I>have seen the driver operate under 2.4.26 dev tree<BR>
</I>><I>from ppc.bkbits.net where this problem does not occur.<BR>
</I>><I>One difference I have noticed is that during<BR>
</I>><I>initialization of the 2.6.7 kernel, I do not get the<BR>
</I>><I>following output.<BR>
</I>><I>Buffer-cache hash table entries:<BR>
</I>><I>Page-cache hash table entries:<BR>
</I>><I>The filemap.c, where the "Page-cache " printk resides<BR>
</I>><I>in 2.4, looks heavily reworked, so I don't suspect<BR>
</I>><I>this is an issue?<BR>

You should sync up with Brian Waite (look at CC: list) who has been<BR>
looking at writing a new enet driver for the 2.6 kernel using the latest<BR>
bridge support code. You can get a look at the latest support code by<BR>
cloning bk://source.mvista.com/linux-2.5-marvell. Note the the mpsc<BR>
driver that's there still isn't working correctly.<BR>
