I expect it to be a kernel setting: CONFIG_SERIAL_8250_NR_UARTS=4 Does mknod+setserial work? (The device node will get lost on reboot, but does the device work as long as the box is not rebootet?) Hello,
>Does mknod+setserial work?
>(The device node will get lost on reboot, but does the device work as long as
>the box is not rebootet?)
No (as stated above). I always get for higher minor numbers:
ttySx: No such device or address
Then it's not a udev/hotplug issue. No idea besides that the CONFIG_SERIAL_8250_NR_UARTS may need to adapted to support more than 4 ports. Not sure! Reassign. Maybe a kernel configuration of CONFIG_SERIAL_8250_NR_UARTS? Fixed. Will be in the next release and the next security update kernel. |
I recently installed an SUSE 10.0 system on my somewhat older computer and now have a little problem with the serial ports. I have an server with 1 normal serial port and a multiport serial card (lspci output): 00:0a.0 Serial controller: Oxford Semiconductor Ltd OX16PCI954 (Quad 16950 UART) function 0 (prog-if 06 [16950]) Subsystem: Oxford Semiconductor Ltd: Unknown device 0000 Flags: medium devsel, IRQ 10 I/O ports at c400 [size=32] Memory at cfff6000 (32-bit, non-prefetchable) [size=4K] I/O ports at c000 [size=32] Memory at cfff5000 (32-bit, non-prefetchable) [size=4K] Capabilities: <access denied> The system setup only initialized 4 serial ports: ttyS0 - external serial ttyS1 - probably nowhere connected, but existing ttyS2 - serial card port 1 ttyS3 - serial card port 2 port 3 and 4 are missing: boot.msg: --snip-- <6>serio: i8042 AUX port at 0x60,0x64 irq 12 <6>serio: i8042 KBD port at 0x60,0x64 irq 1 <6>Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing enabled <4>ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A <4>ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A <4>ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A <4>ACPI: PCI Interrupt Link [LNKC] enabled at IRQ 10 <4>PCI: setting IRQ 10 as level-triggered <6>ACPI: PCI Interrupt 0000:00:0a.0[A] -> Link [LNKC] -> GSI 10 (level, low) -> IRQ 10 <4>ttyS2: detected caps 00000700 should be 00000100 <4>ttyS2 at I/O 0xc400 (irq = 10) is a 16C950/954 <4>ttyS3: detected caps 00000700 should be 00000100 <4>ttyS3 at I/O 0xc408 (irq = 10) is a 16C950/954 --snip-- Previous there was an SuSE9.1 installed, which detected the serials as: device port irq ttyS0 0x3F8 4 ttyS1 0x2F8 3 ttyS14 0x400 10 (now ttyS2) ttyS15 0x408 10 (now ttyS3) ttyS44 0x410 10 ttyS45 0x418 10 I digged into the system, but did not find out, how the automatic device handling works into detail and did not find any solution. I tried setting up this using mknod and setserial, but it seems this is no longer possible? I can provide any additional information if this helps. Would be nice to get this fixed.
