| |
Approximate sequence of event:
1. script which builds allmodconfig on 11 targets is left on otherwise idle machine. Logged in on VT1. Logged of X. 2. After 5 hours I return, ensure script behaves OK, switch to X and see black screen. 3. Now, trying to switch between VTs and X gives nothing but black screen. 4. Alt+SysRq+K. After several seconds black screen switches to black screen with text cursor in the upper-left corner. 5. Futher attempts to switch and SysRq+Ki'ing gave nothing. 6. In a minute or so X login prompt reappeared. Mouse os OK. Keyboard is not. In particular, typing username doesn't work. 7. By some miracle, typing became OK (probably after I hit Ctrl, not sure). I login to X successfully and fire up mutt to mail bugreport. 8. Devil turned me to switch to VT again... 9. goto #5. 10. Cold reboot.
The overall feeling is that X left without human interaction starts to reacts slooowly (probably after blanking kicks in?).
This is semi-reproducable, as in, I can't reproduce it at will but the very same thing occured yesterday.
Now version numbers. All the above happened with 2.6.15-977127174a7dff52d17faeeb4c4949a54221881f
Yesterday it was 2.6.15-5367f2d67c7d0bf1faae90e6e7b4e2ac3c9b5e0f or 2.6.15-0aec63e67c69545ca757a73a66f5dcf05fa484bf, I don't remember. These are just top entries in grub.conf.
