When booting my Thinkpad with a stock 2.1R kernel, either compiled with
or without PSM_NO_RESET, I get the following;
Dec 7 22:56:03 paddy /kernel: psm0 not found at 0x60
The patch below allows it to attach and data to be read from the device:
Dec 7 23:19:15 paddy /kernel: psm0 at 0x60-0x63 irq 12 on motherboard
Note that this driver is having other problems as well, like returning
EAGAIN on a read(), even when O_NDELAY isn't set.
I tried running XFree-3.1.1 (from the 2.0.5R distr) on my 2.1R setup,
and the keyboard is indeed completely dead. Don't think it is related
to the psm driver however, since I had the same problems when using
a Logitech mouse on the serial port.
This weekend, I will try XFree-3.1.2 from the 2.1R distr to see
whether it makes a difference. But for now, it seems that there is
something in the combination PCVT + scanset 2 + Xfree that is broken,
since PCVT + Xfree(-3.1.1) works fine on my 2.1R desktop system.
Anybody out there with a _working_ FBSD2.1R + PCVT + scanset 2 + Xfree
setup ?
