| |
When I debug the driver I found before Detected HW hang, driver unable to clean and reclaim the resources:
1457 while ((eop_desc->upper.data & cpu_to_le32(E1000_TXD_STAT_DD)) && <== at here upper.data always is 0x300 1458 (count < tx_ring->count)) { <--- snip ---> 1487 }
I checked all driver codes I did not found anywhere will set the upper.data with E1000_TXD_STAT_DD, I guess upper.data be set by hardware? If OS is 32bit system, what which happen?
Thanks in advance, Joe
