As for version, see $ uname -a Linux jorge 2.6.26.6 #1 Fri Oct 10 00:52:35 BRT 2008 i686 AMD Athlon(tm) XP 2600 + AuthenticAMD GNU/Linux (although, at the time of the problem, it might have been 2.6.26.5) The computer froze during an emerge of multiple ebuilds (I couldn't know if the emerge had finished or not, but I intensely hope it had - I hate system inconsistencies and filesystem corruptions). The system were completely unresponsive to fn and the magic sysrq keys, except o. In fact, even the keyboard leds were unresponsive AFAIR (as far as I recall). Note: Despite the system *seeming* unresponsive to the other keys, *maybe* they were indeed effective, and I did the whole "r, e, wait 5 seconds, i, s, wait 5 seconds, u, wait 5 seconds, o" hoping that this would cleanly shutdown my computer. AFAIR, the next boot did indicate that the filesystem had been cleanly umounted) On 2008-10-18 it happened again. Using vanilla sources 2.6.26.6. Again, it was after an emerge (but it wasn't immediately after, it was some minutes later). For the record, I am using a tmpfs on PORTAGE_TMPDIR (and it is 1536 MB, far more than enough for emerging the programs I was emerging - gimp-help, yasm, libpcre, subversion, giflib - and I have 1 GB RAM and 972 MB of swap - and I was not running any memory-intensive apps (just enlightenment, gkrellm, pidgin, and firefox viewing a single page on Ubuntu wiki) The emerge went fine with absolutely no errors. Some minutes later, when I was preparing to shutdown the system, the system became unresponsive just after I tried to close pidgin. It seems that the system becomes completely unresponsive to keyboard (except the magic sysrq keys); fn , backspace , , nothing responds. The screen is completely frozen (so I don't know if the computer responds to the mouse). The system itself isn't frozen though - I have cron jobs that beep every 15 minutes (to keep me informed of the time), and I heard the expected beep when the time reached 7:00 (I woke up early, at 5:45). I then performed r, but the system seemed still unresponsive to keyboard. I left the system idle for more than 30 minutes, to see if it would recover. It didn't. I then rebooted with the EISUB sysrq keys combination. The system indeed responded to theses keys - it rebooted and, on the next boot, the filesystem was reportedly clean. I was using e17. Since i changed to Xfce, I haven't had this problem. It is very possible, though, that this was just a coincidence, and the bug is not e17's fault -- Software is like sex: it is better when it is free - Linus Torvalds
