Subject: Re: [PATCH] tc35815: Remove a wrong netif_wake_queue() call which
 triggers BUG_ON

From: Atsushi Nemoto <>
Date: Sat, 20 Feb 2010 00:13:58 +0900

> The netif_wake_queue() is called correctly (i.e. only on !txfull
> condition) from txdone routine.  So Unconditional call to the
> netif_wake_queue() here is wrong.  This might cause calling of
> start_xmit routine on txfull state and trigger BUG_ON.
> This bug does not happen when NAPI disabled.  After txdone there

> In this driver NAPI was enabled on 2.6.33-rc1 so this is
> regression from 2.6.32 kernel.
