uart0 not seen in dmesg which i think is def related:

Jun  9 22:59:31 asd getty[796]: open /dev/ttyu0: No such file or directory

(tried disabling ttyu0 and only having ttyu1 but no luck)

#ttyu0  "/usr/libexec/getty std.57600"  vt100   onifconsole  secure
ttyu1   "/usr/libexec/getty std.57600"  vt100   onifconsole  secure

     uart1: <16550 or compatible> port 0x2f8-0x2ff irq 3 on acpi0

Whereas on a currently working serial system i see uart 0 and 1

///uart0: <16550 or compatible> port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0//
//    uart0: console (57600,n,8,1)////
//    uart1: <16550 or compatible> port 0x2f8-0x2ff irq 3 on acpi0//
is this just a serial port driver issue on com1?

(altho i see all serial stuff till login)
