Hi,
we're using serial consoles on most servers for maintenance etc.
This is usually no problem.
Recently, however, we got our first SLES10 servers and almost
immediately noticed annoying "hangs" during the boot or autoinstall
phase, where the server simply stops and continues only after
a keypress. This is particularly annoying since autoinstallation is about
*not* having to press keys.
The problem persists for all possible combinations of flow control
and baud rates (9600 and 19200 were tested).
This problem was not seen with SLES9 on the same hardware (and with the
same serial cabling).
Our configuration:
Tyan S3992G3NR mobo with 3291 BMC
SLES10 with recent patches installed (2.6.16.21-0.25-smp kernel)
BIOS (and only the BIOS) output redirected to COM1, 19200,8,n,1 with hw
flow control
Kernel cmdline: .... console=tty0 console=ttyS0,19200n8
Has anyone else seen this behaviour and found a remedy ?
Regards,
Norbert Paschedag
