The kernel used was a 2.6.23-rc5 snapshot from Sep 4th, 2007 taken from the linux-mips.org tree (as stated by the revision of the patch provided). There is no version that can be considered working as the change to add the printk() to register_console() went in before drivers/serial/zs.c was added and the old drivers/tc/zs.c driver might have been to sloppy to handle such bits as the transmitter enable properly. I may investigate.
Chances are nobody tried any version of the kernel from the period between the printk() was added and drivers/tc/zs.c removed with the DECstation; I have not.
Anyway, I did confirm keeping the transmitter enabled all the time makes the problem go away.
