Thanks for the update.

Do you have a pointer to the patch, please?

Yes, it's referenced in:

http://marc.info/?l=linux-netdev&m=125104144706982&w=2

Which was for 2.6.30.5  The same patch still applies on 2.6.31-rc7 with offset and that's actually where I tested it.  That resolved the timeouts for me.  I believe Krzysztof was going to get a patch in to -stable as well as for .31-rc before final.

commit 6ff9c2e7fa8ca63a575792534b63c5092099c286
Author: Krzysztof Hałasa <khc@pm.waw.pl>
Date:   Sun Aug 23 19:02:13 2009 -0700

    E100: fix interaction with swiotlb on X86.
    
    E100 places it's RX packet descriptors inside skb->data and uses them
    with bidirectional streaming DMA mapping. Data in descriptors is
    accessed simultaneously by the chip (writing status and size when
    a packet is received) and CPU (reading to check if the packet was
    received). This isn't a valid usage of PCI DMA API, which requires use
    of the coherent (consistent) memory for such purpose. Unfortunately e100
    chips working in "simplified" RX mode have to store received data
    directly after the descriptor. Fixing the driver to conform to the API
    would require using unsupported "flexible" RX mode or receiving data
    into a coherent memory and using CPU to copy it to network buffers.
    
    This patch, while not yet making the driver conform to the PCI DMA API,
    allows it to work correctly on X86 with swiotlb (while not breaking
    other architectures).

This fixes 303d67c2 which has been included in at least the 2.6.27.29
and 2.6.30.5 stable releases so I think this should be a candidate for
those stable branches too.

Absolutely, I'll take care of this.

please let me know.

If you know of any other unresolved regressions from 2.6.30, please let me know
either and I'll add them to the list.  Also, please let me know if any of the
entries below are invalid.

Each entry from the list will be sent additionally in an automatic reply to
this message with CCs to the people involved in reporting and handling the
issue.
