Hi Sebastian,
yes, after some minor tweaking (retval -> ret) it builds and
traceback is gone! So it's a progress.
However it seems that ports are behaving a bit strange, but
I'm only testing it the blunt way now, by cating file to /dev/ttySx
without anything attached (but on older kernels when the port was OK,
it was OK as well)
now the cat just hangs for long time, similar problem with setserial -g:
0.000538 lstat("/dev", {st_mode=S_IFDIR|0755, st_size=3520, ...}) = 0
0.000205 lstat("/dev/ttyS3", {st_mode=S_IFCHR|0660, st_rdev=makedev(4, 67), ...}) = 0
0.000212 fstat(3, {st_mode=S_IFCHR|0660, st_rdev=makedev(4, 67), ...}) = 0
0.000128 ioctl(3, TIOCGSERIAL, 0x7ffc0a9cfac0) = 0
0.000111 write(1, "/dev/ttyS3, UART: 16750, Port: 0"..., 47/dev/ttyS3, UART: 16750, Port: 0xe088, IRQ: 11
) = 47
0.000168 fstat(3, {st_mode=S_IFCHR|0660, st_rdev=makedev(4, 67), ...}) = 0
0.000134 close(3) = 0
30.206511 open("/dev/ttyS4", O_RDWR|O_NONBLOCK) = 3
0.000479 lstat("/dev", {st_mode=S_IFDIR|0755, st_size=3520, ...}) = 0
0.000192 lstat("/dev/ttyS4", {st_mode=S_IFCHR|0660, st_rdev=makedev(4, 68), ...}) = 0
the close(x) seems to always take 30s now.. ttyS0 is fine..
why could that be?
