Yes, I have it turned on in the kernel. # grep CONFIG_USB_STORAGE_DEBUG /etc/kernels/kernel-config-x86_64-2.6.32-gentoo-r7 CONFIG_USB_STORAGE_DEBUG=y I don't understand why it just started to be a problem. I've had this kernel for almost four months. Shouldn't the log's be rotated and purged? I've been using the default kernel config from the install. I'll make a new kernel with it turned off. Thanks, dhk
