Hi,
I've decided to finally start playing with -current a day or five ago.
One of the first experiences was a funny syscons keyboard freeze when
using a custom kernel with 'options VESA' and the logo_saver kernel module.
The symptoms: after the saver relinquishes control, the keyboard is kind of
frozen; 'kind of', because the controlling keys still work - Alt+Fx switches
consoles, Ctrl-PrtScr escapes to DDB, Alt-arrows also switch consoles.
However, any 'real' key typed has no effect - nothing appears on the screen
and no action is taken - not on the login prompt, not on the shell cmdline,
not within an editor. Even Ctrl-Alt-Del is ignored :( The only way to
restart the system is by calling restart or panic inside DDB.
Attached is my kernel config (derived from GENERIC), and a backtrace of
the panic crashdump. More details, including the crashdump and the kernels
(booted and debugging) shall be posted shortly on a website - they are
currently being uploaded via a slow modem link, and the vmcore is *huge*,
even when bzipped :) The webpage index is already there, so are the debug
logs and the kernel images, the vmcore shall take a bit longer to arrive.
Details at http://mail.orbitel.bg/~roam/crash/logo_vesa.html
The *.2.* files are from a -current source tree as of Dec 10, 16:58 EEST.
The *.1.* files are from a source tree as of.. mm.. yesterday, I think;
however, I do not think many relevant changes have been made to either
syscons or the logo_saver source in the meantime.
If I'm doing something much wrongly, feel free to beat me up with the
heaviest cluestick around :)
G'luck,
Peter
PS. I do not know anything about the syscons/saver interaction; as a matter
of fact, i know next to nothing about syscons itself. So things might take
a bit of handholding here :)
PPS. Please CC: me, as I'm not on -current (or just honor the Mail-Followup-To
header ;)
