I copied the debian-ia64 list, which is probably a better place to
start.
The HP management processor contains a virtual UART that is
implemented partly in hardware and partly in firmware. There
have been a number of issues related to the fact that it is not
a real 16550 UART.
Here's a summary of the issues I know about. My guess is that
you're seeing the first one, so I'd start by checking your
MP firmware revision.
* serial console device lockup
- system responds via network
- no input or output via serial console device
- occurs when application opens device while transmit buffer contains
polled-mode kernel output, typically during boot
- INIT dump shows CPUs in idle loop
- after system reset, MP event log shows "BOOT_PLAT_CONSOLE_DEV_FAILED"
or similar event
- hang is resolved only by MP reset; system reset is not sufficient
- resolved in MP firmware E.03.29 or later (rx16x0, rx26x0, rx4640, rx5670)
- resolved in MP firmware F.01.39 or later (rx3600, rx6600)
* serial console driver deadlock
- system completely unresponsive to all devices
- INIT dump shows one or more CPUs in ia64_spinlock_contention,
waiting for a ttyS UART lock (lock ptr in r31)
* serial device out of sync with driver
- system responds via network
- serial output stops
- sending serial input generates an interrupt that causes up to 16
more characters of output
- re-opening the device fixes the problem
* serial device drops interrupt
- system responds via network
- serial output stops
- sending serial input generates an interrupt that resolves the problem
