Peter Anvin" , Jack Steiner , Thomas Gleixner , x86@kernel.org, linux-kernel@vger.kernel.org Subject: [PATCH 0/2] printk: Allocate log buffer as early as possible Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org On larger systems, information in the kernel log is lost because there is so much early text printed, that it overflows the static log buffer before the log_buf_len kernel parameter can be processed, and a bigger log buffer allocated. Distros are relunctant to increase memory usage by increasing the size of the static log buffer, so minimize the problem by allocating the new log buffer as early as possible. --
