[Armadillo:00382] uClinux crash

[Tomáš Paukrt]

I am developing GPRS router with uClinux. I am running the 2.4.22-uc0-aj1 kernel from the aj20050105 uClinux distribution. The system is working correctly, but when I do a telnet connection and execute few commands in shell during transfering data through GPRS, system suddenly freeze without printing any error message into console. It also happen when I only transfer data through connected GPRS modem for about one hour. I tried pppd 2.4.1 instead of 2.3.8, but it didn't help.

Thanks for any hint or suggestion.
