Date: Mon, 21 May 2007 14:51:35 -0700 From: Auke Kok <auke-jan.h.kok@...el.com> To: jeff@...zik.org, stable@...r.kernel.org, greg@...e.de Cc: e1000-devel@...ts.sourceforge.net, netdev@...r.kernel.org, auke-jan.h.kok@...el.com, davej@...hat.com, herbert@...dor.apana.org.au Subject: [PATCH] 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.
