(Newport) console problems on IP22
Hi,
Martin Michlmayr offered a build of 2.6.29-rc5 for test to debian-mips, and that kernel is showing console-related issues on my IP22.
I'm not sure what's going, so here are my observations:
- the Newport console is not detected anymore
- getty process stuck
root 1226 98.7 0.0 0 0 tty1 Rs+ 19:48 9:22 [getty]
gettys on tty[2-6] might also be stuck somewhere. Can't strace the getty on tty1 (operation not permitted) and strace on tty[2-6] attaches to the process but doesn't print anything and is stuck from here on. Cannot detach or anything. Processes are of course unkillable.
- dmesg fills up with
tty_release_dev: tty1: read/write wait queue active!
No keyboard/screen attached, serial console only.
Does that ring any bell wrt recent tty changes? Any idea?
JB.

Looks like the strace on the getty process on tty2 led to something hanging to the point my serial console on ttyS0 was hung after that.
But I could still log in via SSH, so the kernel keeps running fine despite that.
