Fixed, thanks to this thread: http://mailing.freebsd.questions.narkive.com/1jubDzGu/r220-s-with-serial Adding hw.uart.console="io:0x2f8,br:57600" to /boot/loader.conf seems to have fixed the issue. -----Original Message----- From: Lavery, Benjamin (IT Enterprise Services) Sent: 08 August 2016 11:48 To: 'freebsd-questions@freebsd.org' Subject: FW: Serial redirection halts on Dell PowerEdge 1955 Blade (mfsBSD) Good morning all, (Apologies, cross-posting from freebsd-hardware) I have been given an old Dell PowerEdge chassis filled with PowerEdge 1955 blades. I also have a FreeNAS which I'm using to serve DHCP addresses and TFTP for PXE booting. I can get the blades to PXE boot (I'm using pxelinux to load mfsbsd-10.3-RELEASE-amd64), but the serial redirection is only working for the first part of the boot sequence. After select mfsBSD at the menu, I get the following (verbose boot chosen at the boot menu): Loading memdisk... ok ok e820: 0000000000000000 00000000000a0000 1 e820: 0000000000100000 00000000cfea8000 1 e820: 00000000cffa8000 000000000000fc00 3 e820: 00000000cffb7c00 0000000000048400 2 Total size needed = 2513 bytes, allocating 3K Old dos memory at 0x8a000 (map says 0xa0000), loading at 0x89400 1588: 0xffff 15E801: 0x3c00 0xcbba INT 13 08: Success, count = 1, BPT = 0000:0000 Drive probing gives drive shift limit: 0x82 old: int13 = ca001da6 int15 = f000f859 int1e = f000efc7 new: int13 = 8940000a int15 = 894003ba int1e = f000efc7 Loading boot sector... booting... /boot/config: -D FreeBSD/x86 boot Default: 0:ad(0p2)/boot/loader boot: BTX loader 1.00 BTX version is 1.02 console comconsole failed to initialize Consoles: internal video/keyboard serial port BIOS drive A: is disk0 BIOS drive C: is disk1 BIOS drive D: is disk2 BIOS 549kB/3353216kB available memory FreeBSD/x86 bootstrap loader, Revision 1.1 (root@releng1.nyi.freebsd.org, Fri Mar 25 02:04:38 UTC 2016) \oading /boot/defaults/loader.conf lapic3: Routing NMI -> LINT1 lapic3: LINT1 trigger: edge lapic3: LINT1 polarity: high lapic7: Routing NMI -> LINT1 lapic7: LINT1 trigger: edge lapic7: LINT1 polarity: high MADT: Interrupt override: source 0, irq 2 ioapic0: Routing IRQ 0 -> intpin 2 MADT: Interrupt override: source 9, irq 9 ioapic0: intpin 9 trigger: level ioapic0 <Version 2.0> irqs 0-23 on motherboard ioapic1 <Version 2.0> irqs 32-55 on motherboard ioapic2 <Version 2.0> irqs 192-215 on motherboard cpu0 BSP: ID: 0x00000000 VER: 0x00050014 LDR: 0x00000000 DFR: 0xffffffff lint0: 0x00010700 lint1: 0x00000400 TPR: 0x00000000 SVR: 0x000001ff timer: 0x000100ef therm: 0x00010000 err: 0x000000f0 pmc: 0x00010400 wlan: <802.11 Link Layer> snd_unit_init() u=0x00ff8000 [512] d=0x00007c00 [32] c=0x000003ff [1024] feeder_register: snd_unit=-1 snd_maxautovchans=16 latency=5 feeder_rate_min=1 fe eder_rate_max=2016000 feeder_rate_round=25 null: <null device, zero device> nfslock: pseudo-device ‘‘‘‘‘‘‘‘‘‘‘ The odd glitch (‘) is me trying to input after output stops. I'm accessing the console by TELNETing to the blade chassis, and connecting to the blade console. I believe this runs at a baud rate of 57600. Because of this I've modified the following files within mfsBSD: etc/ttys (from inside mfsroot.gz) # Serial terminals ttyu0 "/usr/libexec/getty std.57600" vt100 on secure ttyu1 "/usr/libexec/getty std.57600" dialup on secure ttyu2 "/usr/libexec/getty std.57600" vt100 off secure ttyu3 "/usr/libexec/getty std.57600" vt100 off secure # Dumb console dcons "/usr/libexec/getty std.9600" vt100 off secure boot/loader.conf boot_multicons="YES" boot_serial="YES" comconsole_speed="57600" console="comconsole" The Java console from the chassis web interface doesn't work on my laptop, but via another server I've been able to grab the attached screenshot. It states: getty[706]: open /dev/ttyu0: No such file or directory Unfortunately the Java console doesn't work well enough for me to use to log in and get at any settings (getting it to load that far took 10 minutes...) The blades BIOS is set up to redirect to COM2 (it's either that or be disabled) and to emulate vt100/vt200 (could also be ANSI, but this doesn't seem to allow input). Would anyone have any ideas about how I can get console redirection working past this point? Or where I can look to get more information?
