Hello. I have been using a serial console to capture an OOPS I have been encountering with the ide system. I have been using 2.2.12 + ikd + serial console to do my work, as I needed the NMI oopser from ikd.
I just tried switching to 2.3.18, to use ingo molnar's built in NMI oopser that works great. However, I can't get the serial console to work all the way through the boot.
I had the same experience with 2.3.18 and 2.3.18ac10. If serial console is enabled in kernel and with console flags, everything goes well printing console boot output to the serial port, until I get to here:
> [kernel boot log, already in progress...] > Starting kswapd v1.6 > Detected PS/2 Mouse Port. > Serial driver version 4.30 with SHARE_IRQ SERIAL_PCI PCI_IOMEM enabled
After this point, nothing further is written to the serial port. In fact, once I've booted I can't send anything else to the serial port either.
If I do dmesg > /dev/ttyS1 cat /proc/tty/driver/serial shows tx incrementing each time, but nothing is displayed.
If I disable serial console in the kernel, everything works as expected... no serial console output, but dmesg > /dev/ttyS1 shows up fine. This configuration also works fine with 2.2.12
ttys are: ttyS00 at 0x03f8 (irq = 4) is a 16550A ttyS01 at 0x02f8 (irq = 3) is a 16550A
config is RH60 base, abit-bp6, dual c366 on board serial ports. Running SMP.
Regards,
Tom
