Are you sure you posted the right config? The modular serial 8250 build works fine for me for 2F, and also your config works. However, for Loongson 3 build I'm able to reproduce the same. Possibly caused by c7d3555ac075 (MIPS: Loongson 3: Add HT-linked PCI support), which enables HT_PCI and adds loongson_sysconf reference to serial.ko, but the symbol is not exported to modules. In loongson.h: #if defined(CONFIG_HT_PCI) #define LOONGSON_PCIIO_BASE loongson_sysconf.pci_io_base #else #define LOONGSON_PCIIO_BASE 0x1fd00000 #endif And in loongsong serial.c: uart8250_data[mips_machtype][0].iobase = loongson_uart_base - LOONGSON_PCIIO_BASE; A.
