From mboxrd@z Thu Jan 1 00:00:00 1970 From: Keith Owens Date: Wed, 01 Dec 2004 11:02:35 +0000 Subject: Out of order console initialization on HP CX2600 Message-Id: <7077.1101898955@ocs3.ocs.com.au> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-ia64@vger.kernel.org This problem has been reported against the SLES9 SP1 Beta3 ia64 debug kernel on HP CX2600. The ttySn ports are detected long after console_init() has run, kdb detects no console and shuts down. Why do the ttySn ports get detected after console_init() on HP? Is there anything that can be done to detect ttySn before console_init()? EARLY_PRINTK is not an option, the kernel is compiled for CONFIG_IA64_GENERIC, which disables EARLY_PRINK. <4>Kernel command line: BOOT_IMAGE=scsi1:\efi\SuSE\vmlinuz-2.6.5-7.118-debug root=/dev/sda4 console=ttyS1,9600n8 ro <3>kdb: Initialization failed - no console. kdb is disabled. <4>kdb version 4.4 by Keith Owens, Scott Lurndal.
