I reverted those masking changes in Fedora and the baffling problem with 3Com 3C905 network adapters went away. Before, they would print: eth0: transmit timed out, tx_status 00 status e601. diagnostics: net 0ccc media 8880 dma 0000003a fifo 0000 eth0: Interrupt posted but not delivered -- IRQ blocked by another device? Flags; bus-master 1, dirty 295757(13) current 295757(13) Transmit list 00000000 vs. f7150a20. 0: @f7150200 length 80000070 status 0c010070 1: @f71502a0 length 80000070 status 0c010070 2: @f7150340 length 8000005c status 0c01005c Now they just work, apparently... So why not just revert the change? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
