rx_status= 8188 ( dec ) = 0x1ffc ( hex )
inside the loop ( of course )

The kernel 2.4.16-pre1 have the same problem.
I have tested with BNC cable and UTP cross-link cable; the problem is always
same.
When the machine hang, the key sequence CTRL-ALT-SYS_RQ-U ( umount/force
mount ro ) not work; but the key sequence CTRL-ALT-SYS_RQ-B ( force boot )
work. I not know if the sequence CTRL-ALT-SYS_RQ-S ( sync ) work or none.
