Glad to hear that :-)

1st try was a configured only, out-of-the-box 2.6.8  (copied 
/boot/config* as .config into /usr/src/kernel-source-*) and enbd 2.4.32.

2nd try (after your reply) was enbd 2.4.33 with a configured+built 
2.6.8, same result as with 2.6.15 (cf. below). All builds were done with 
gcc version 3.3.5 (Debian 1:3.3.5-13), all kernel sources are Debian ones.

3rd try was enbd 2.4.33 with a configured+built 2.6.18, didn't compile 
(they removed split-include from scripts/basic).

4th try was enbd 2.4.33 with a configured+built 2.6.15, it compiled with 
lots of "warning: long long int format, s64 arg" (seems to affect only 
message output, though).

Module insertion doesn't show anything unusual (I suppose, the version 
mismatch "Enhanced Network Block Device 2.4.30 $Date: 2002/09/17 
16:33:22 $" in the log doesn't mean anything.).


Finally, upon "make test", the client suffers a SIGSEGV:

/root/enbd-2.4.33/nbd/enbd-maketest: line 348:  4208 Segmentation 
fault      nice -19 $ENBD_CLIENT $OPTCLI


Which details would you need for further investigation?

Unfortunately not, sorry. My AMD64 at home had no more free PCI-slots, 
thus it is located next to my DSL-modem and connected via cat5 to its 
on-board NIC. And here at the lab, we use WiFi only for laptops.
