Subject: tg3 appears to be sick in 2.6.33

Hi,

Ever since I moved post 2.6.32 tg3 seems to be very sick in my Latitude
D630, it discards most of the packages for some reason:

[root@...r-d630 ~]# ethtool -S eth0 | grep rx_
     rx_octets: 35886
     rx_fragments: 0
     rx_ucast_packets: 9
     rx_mcast_packets: 93
     rx_bcast_packets: 237
     rx_fcs_errors: 0
     rx_align_errors: 0
     rx_xon_pause_rcvd: 0
     rx_xoff_pause_rcvd: 0
     rx_mac_ctrl_rcvd: 0
     rx_xoff_entered: 0
     rx_frame_too_long_errors: 0
     rx_jabbers: 0
     rx_undersize_packets: 0
     rx_in_length_errors: 0
     rx_out_length_errors: 0
     rx_64_or_less_octet_packets: 0
     rx_65_to_127_octet_packets: 0
     rx_128_to_255_octet_packets: 0
     rx_256_to_511_octet_packets: 0
     rx_512_to_1023_octet_packets: 0
     rx_1024_to_1522_octet_packets: 0
     rx_1523_to_2047_octet_packets: 0
     rx_2048_to_4095_octet_packets: 0
     rx_4096_to_8191_octet_packets: 0
     rx_8192_to_9022_octet_packets: 0
     rx_discards: 304
     rx_errors: 0
     rx_threshold_hit: 0

The above on last night pull from Linux (so 2.6.33+).

Everything works fine if I use wireless or another wired card (Realtek in 
cardbus slot):

[root@...r-d630 ~]# lspci | grep -ri net
