Dear Misc Listeners,
After the installation of a Logilink PC0017 4x serial puc(4) addon
card, my system initially hung at "setting tty flags" at boot.
After a reboot in single-user mode, from now on the hang-ups are
gone away also in multi-user mode but it seems to me that only two
of the four additional serial ports are configured. This will be no
drama since, in fact, I only need two additional serial ports.
I have to correct myself, the hangups occur again from time to time
when booting in multi-user mode and disappear after some intermediate
reboots in single-user mode. I will disassemble that addon card soon.
With best regards,
Jens
The system configures the chip on my Logilink PC0017 card (with four
serial ports) as "NetMos Nm9865".
Following /src/sys/dev/pci/pucdata.c it expects six serial ports

But the imprint on the chip of my Logilink PC0017 card (with four
serial ports) is "MosChip MCS9865" which would correspond to
...
/* "MosChip MCS9865 Quad Serial Port" */
{ PCI_VENDOR_MOSCHIP, PCI_PRODUCT_MOSCHIP_MCS9865, 0x1000, 0x4 },
{ 0xffff, 0xffff, 0xffff, 0xffff },
{
{ PUC_COM_POW2(0), 0x10, 0x0000 },
{ PUC_COM_POW2(0), 0x14, 0x0000 },
{ PUC_COM_POW2(0), 0x18, 0x0000 },
{ PUC_COM_POW2(0), 0x1c, 0x0000 },
},
...
In fact, the card was offered to me to have the MosChip MCS9865.
Since I do not believe that the system detects a wrong chip,
this means that the chip seems to have a wrong imprint ...
With best regards,
Jens
The imprint on the chip is MOSCHIP MCS9865IV-AA. Following the manual
I have tried to avoid the misconfiguration of my Logilink PC0017 card
by applying some experimental diff to handle the case of four instead
of six serial ports:

Indeed, after recompilation of the kernel and reboot now my four port
serial card seems to be configured successfully:
...

...
Nevertheless, the hangups at "setting tty flags" still occur from
time to time when booting in multi-user mode and disappear after
intermediate reboot(s) in single-user mode. This corresponds to
the situation which has been reported yesterday by Nick and Jan
even in the case of two port serial cards of similar type.

Jens
