e1000: Don't enable polling in open() (was: e1000: assertion hit in e1000_clean(), kernel 2.6.21.1)
Herbert Xu wrote:
"netif_poll_enable can only be called if you've previously called
netif_poll_disable. Otherwise a poll might already be in action
and you may get a crash like this."
Removing the call to netif_poll_enable in e1000_open should fix this issue,
the only other call to netif_poll_enable is in e1000_up() which is only
reached after a device reset or resume.
