Hi, With a Lemote mini-pc 2F6004:
% cat /proc/cpuinfo system type : lemote-fuloong-2f-box processor : 0 cpu model : ICT Loongson-2 V0.3 FPU V0.1 BogoMIPS : 530.43 wait instruction : yes microsecond timers : yes tlb_entries : 64 extra interrupt vector : no hardware watchpoint : yes, count: 0, address/irw mask: [] ASEs implemented : shadow register sets : 1 core : 0 VCED exceptions : not available VCEI exceptions : not available I tried enabling an external USB NIC, using a TrendNet TU2-ET100, which is supported by usbnet driver: http://www.linux-usb.org/usbnet I'm using the debian experimental kernel: % uname -a Linux mini-0 2.6.37-trunk-loongson-2f #1 Fri Jan 7 10:10:56 UTC 2011 mips64 GNU/Linux Under debian gnu/linux. Notice I installed debian by ffirst installing gnew-sense, sincer debian doesn't suppot lemote under its installers yet. I could actually see the external NIC work for a little while, and after copying from another machine a 104M file, the NIC was just shutdown: [ 4763.132000] usb 1-1: new high speed USB device using ehci_hcd and address 5 [ 4763.276000] usb 1-1: New USB device found, idVendor=0b95, idProduct=7720 [ 4763.276000] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 4763.276000] usb 1-1: Product: AX88772 [ 4763.276000] usb 1-1: Manufacturer: ASIX Elec.

Recently I had problems with the internal NIC most probably due to HW problems, on the checksum computation by HW... I need to enable a 2nd NIC in order to make the mini-pc work as a gateway mini-server. Perhaps someone else has experiences with this mini-pc, and has already make an external NIC work already, and if so any hints would be appreciated. Also any hints on how to debug and file a debian experimental linux bug, that'd also work out, :-) If faster solution is to use an external NIC known to work, please let me know so I can try acquiring it...
