| |
Hi,
While testing the final 3.15, I noticed the serial console (sunsab) does not work anymore on Sun Ultra.
It will tx fine the console output during the boot. But then I try to type something e.g. at the login: prompt, it behaves oddly: it re-transmits some old output, and then stalls for a few secs, usually for each character. Typed characters are however received correctly. But the console is impossible to use...
I bisected this to:
717f3bbab3c7628736ef738fdbf3d9a28578c26c is the first bad commit commit 717f3bbab3c7628736ef738fdbf3d9a28578c26c Author: Seth Bollinger <sethb@digi.com> Date: Tue Mar 25 12:55:37 2014 -0500
