 |
|
I have a server with console on serial port. I connect to it, using standard null-modem cable.
Everything used to work fine, but i switched to gcc-3.4, updated a lot in system, rebuilt world,etc..
now, when i:
1) start minicom
2) power the server
i see boot messages from server`s kernel, but quickly all stops in the minicom.
server works fine, i`m able to ssh to it, i`m able to connect to it`s serial port from notebook,using same cable and terraterm.
minicom starts consuming 100% cpu, but doesn`t hang(i`m able to exit and all becomes normal).
when i attach to it with strace, i see following:
| Code: |
ioctl(3, TIOCMGET, [0]) = -1 EIO (Input/output error)
select(4, [0 3], NULL, NULL, {1, 0}) = 1 (in [3], left {1, 0})
read(3, "", 127) = 0
|
currently, i`m using gentoo-sources-2.6.15-r1.
What can problem be related to? bad serial port on my motherboard, kernel bug ? minicom problems?
