I will try > to find where to enlarge it. I have posted the partial result to: use 'dmesg -s 100000' if it's just dmesg(8) that needs help. If it's the kernel buffer filling up, you can rebuild the kernel after changing CONFIG_LOG_BUF_SHIFT, but it's easier just to boot using this: log_buf_len=n Sets the size of the printk ring buffer, in bytes. Format: { n | nk | nM } n must be a power of two. The default size is set in the kernel config file. --- ~Randy *** Remember to use Documentation/SubmitChecklist when testing your code *** - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
