tg3 fails with x86_64 (but works with i386)

[Frank Steiner <fsteiner-mail1@bio.ifi.lmu.de>]

Hi,

I've two 3com 3C996B-T network cards (lspci says it's
a Broadcom BCM5701 chip) in Asus A8V boards with an
AMD64 4000+ cpu. Booting a x86_64 version of the
2.6.12.2 kernel, the tg3 module complains

  tg3.c: v3.31 (June 8, 2005)
  tg3_test_dma() Write the buffer failed -19
  tg3: DMA engine test failed, aborting.

and no eth0 is available. However, when booting a 32bit
version of 2.6.12.2, the cards work well with the tg3
module. So it must be some problem in the x86_64
specific kernel code.

Any ideas what I could do? What further information can
I provide?

cu,
Frank
