I'm done with bisecting it: the first bad commit is: commit dabc5c670d3f86d15ee4f42ab38ec5bd2682487d Author: Matt Carlson <mcarl...@broadcom.com> Date: Thu May 19 12:12:52 2011 +0000 tg3: Move TSO_CAPABLE assignment This patch moves the code that asserts the TSO_CAPABLE flag closer to where the TSO capabilities flags are set. There isn't a good enough reason for the code to be separated. Signed-off-by: Matt Carlson <mcarl...@broadcom.com> Reviewed-by: Michael Chan <mc...@broadcom.com> Signed-off-by: David S. Miller <da...@davemloft.net> On the other hand, losing the SoL console even temporarily during boot (as it happens with a minimal kernel before this commit) isn't nice either. I'll try to look after that, too, just mentioning it here... -- Regards, Feri. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
