Title:
  Sky2 ethernet failing randomly with Marvell 88E8056 gigabit

Status in Linux:
  Invalid
Status in linux package in Ubuntu:
  Invalid
Status in linux-source-2.6.22 package in Ubuntu:
  Won't Fix

Bug description:
  Binary package hint: linux-source-2.6.22

  Since Ubuntu Feisty the sky2 ethernet adapters have not been stable.
  Also after the bugfixes in kernel 2.6.22-11.32 (which is my current
  kernel) the failures continue to happen. Earlier on the problem
  appeared while doing big file transfers (>1 GB), as of 2.6.22-11.32 it
  now looks more like random freezes (without traffic). Doing a restart
  of the network (/etc/init.d/networking restart) does not work. As I
  have two sky2 adapters available, switching over to the other plug
  brings the network back up. When also this one fails, I have to resort
  to a reboot.

  In the the dmesg log I find usually the following information after a
  crash:

  Is there any hope this bug will be resolved, or should I just change
  to the proprietary sk86lin driver?
