hi dave,
i applied the patch to the v2.6.35.2 kernel and it works now. with the
help of the patch file my colleague and i found out that the flasher
tool "lpc2k_pgm" needed to be updated to work with the actual stable
kernel versions, so we fixed our flasher tool and now it works with the
actual stable releases(for example v2.6.35.4). it was a problem with
handling the DTR/RTS lines. so from our side the problem is fixed now.
thanks for your help,
stephan

I did a quick search for your hardware and it seems that your board is
using the DTS/RTS lines to put the MCU in reset. The way modem control
is handled has changed in the ftdi_sio driver and is likely to be the
cause of your problems.
I've recently had to look into a similar problem. It turns out that the
ftdi_sio driver now manages those lines incorrectly.
Stephan: Would you be able to pick a kernel which has the problem, apply the
attached patch (ftdi_sio.patch) to it, and find out if that resolves your
problem?
