[uClinux-dev] uclinux stability on NET+ARM (hopefully)

I'm using an evaluation board from Netsilicon with an net+arm (net+40) cpu. I have an uclinux kernel version 188.8.131.52pre7arm provided by NET+Lx 1.0.
I can confirm the stability problem that the kernel just freezes if there is to much net load (see http://www.uclinux.org/pub/uClinux/archive/4215.html).
I have written a small program wich just loads many data via nfs/smb. I put it as attachment. When I use it the system freezes guaranteed after a while. To use the programm you just have to create a big file (i use 600MB) data with many zeros in it (cat /dev/zero > data) and than compile it and use it via an nfs/smb mount point.
Sometimes I get "Kernel panic: Unknown data abort code 33554432 [pc=00052de4, *pc=e8b4000f] LR=00052de4" before crashing. Normally the kernel crashes after maximal 20MB.
Meanwhile I have tested Net+Lx 1.8 but the same error occurs.
Has anybody a stable version of uclinux on net+arm? If so, please let me know.
