Martin has cleaned up the serial and console code. He will commit his | changes tomorrow after he's tested it. In testing the 2.3 kernel on my D320/1 with an Access Port (AP) card as the console, printk() appeared to be broken. The mprint() statements in the boot loader seem to function correctly, and the pdc_putc('.') at the end of realmode_setup() works, but the printk() at the start of iodc_con_init() never outputs. The chassis codes sent out in realmode_setup() do appear properly on the AP console. Now the interesting thing in a D-Class with an AP card installed is that the RS-232 connector on the back of the machine is dis-connected from the LASI serial hardware and connected to the AP card hardware. Because of this, regardless of what console path is stored on the machine, the AP card console is what is used, so that there will always be console outptu. When I changed the stored path from the LASI RS-232 path to the AP card RS-232 path, the printk() succeeds. So, there must be something in printk() which is getting confused between what console is actually in use and what console is the stored path. That aside, the kernel appears to hang at the first __put_user() macro called in unsigned long create_som_tables(). Executing a TOC after the hang consitently gives IIA space/offset = 0x00000000 0x00046234.
