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
