It works for me, xl0 card is recognized. But during heavy ftp network traffic the LAPTOP panics. As a test I wanted to download the 5.1 SNAP ISO image from my 5.1-current FreeBSD server (PIII 1GHz, 512 MB DRAM, fxp0). Under Windows XP this ~300 MB file gets transferred with about 9-9.3 MByte / sec. Using FreeBSD 5.1 on the laptop it starts with about 8 MByte/sec grows up to 8.3 KByte/sec but then after 115 MB the transfer stalls. After about one minute the kernel panics. panic: sbflush: cc 4294967244 || mb0 || mbcnt 0 syncing disks, buffers remaining ... 1814 1814 1814 1814 1814 [ repeated ~20 times] giving up on 18 buffers. The kernel was basically a stripped down GENERIC kernel without -currents debugging options.
