It is an IBM ThinkCentre M52 (8215F7G) with:

[    3.202517] Serial: 8250/16550 driver, 32 ports, IRQ sharing enabled
[    3.222927] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[    3.256381] serial8250: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
[    3.328789] 00:0c: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[    3.364454] 00:0d: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A

I did notice that the pulse width was 10ms, I increased that to 200ms.
That did not solve it.
