Hi,
The kernel is 2.6.18 and patched the SDHC update.
The program is a recorder that writing the video and audio to SD continuesly for two days.
This morning, we saw the console syas "ERROR: TOUT waiting for BUSY" and CPU load is heavy.
Then, we killed the program, and the CPU is still busy. The error message does not stop, too.
