Contains an Intel Atom N270 CPU, 2GB RAM, 1 TB SATA Hard-Drive. Mainboard is a MSI IM-945GSE Mini-ITX motherboard. The DVB-S card is a WinTV Nexus-S Rev 2.3 card. Kernel is a custom built kernel: Linux version 2.6.34-rc7 (root@filmdose) (gcc version 4.4.4 (Debian 4.4.4-1) ) #7 SMP Fri May 21 18:06:19 CEST 2010 Channel scan starts fine, finds some channels and after a random duration it crashes. I already tried starting the kernel with nosmp, noapic, and noacpi options but that does not change anything.
