As mentioned in [1] I doubt ethernet as well. For test purposes I boot using ramdisk instead of NFS, so I had no network/NFS access at boot time. Then, I manually mounted NFS from user space and played MP3 via NFS [1]. Anybody with a hint for non-experts what "BUG: scheduling while atomic" wants to tell us? Any idea what is wrong here? IRQ 160 is our GPIO eth0 interrupt. Dirk [1] http://linux.omap.com/pipermail/linux-omap-open-source/2006-November/008490.html
