This turned out to be a real kernel issue, and now 2.6.20.8 is released with a fix for this problem. I still think there's a bug in your userspace program, but the kernel shouldn't die anymore at least :) thanks, greg k-h _______________________________________________ Kernel-janitors mailing list Kernel-janitors@lists.linux-foundation.org https://lists.linux-foundation.org/mailman/listinfo/kernel-janitors
