The problem was reported with kernel-2.6.7-1.441. It seems to be gone with kernel-2.6.7-1.456. At least it is not reproducible after reboot into that kernel. It's a heisenbug! It is back now with a vengeance, still on kernel 2.6.7-1.456. No configuration changes or anything that can explain it. I hope it can be reproduced by someone else. Can you describe your environment in more detail? Is this with a fresh rawhide install? I don't see this in FC2 for example, do you? This problem is a dupe of 128154. Well technically 128154 is a dupe of this problem, but 128154 has better discussion going on. *** This bug has been marked as a duplicate of 128154 *** Changed to 'CLOSED' state since 'RESOLVED' has been deprecated. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040510 Epiphany/1.2.4 Description of problem: Emacs causes a lockup of X when M-x telnet is used. The mouse pointer gets jerky and eventually stops. The keyboard stops responding, even to Num Lock. After a while (say, half a minute) the system recovers. Load avg goes up to 15 or so, and CPU stays at 100% for the duration. With xemacs the load spike is there as well, but the system doesn't stop completely. Version-Release number of selected component (if applicable): emacs-21.3-14 How reproducible: Always Steps to Reproduce: 1. Start emacs 2. M-x telnet sunsite.dk 80 3. Actual Results: The load avg goes to 15 and X becomes unresponsive Expected Results: telnet should have connected to port 80 on sunsite.dk Additional info: This may or may not be related to pty handling, as strace shows a lot of these: 29048 12:54:23 open("/dev/ptye5", O_RDWR) = -1 ENXIO (No such device or address) 29048 12:54:23 --- SIGALRM (Alarm clock) @ 0 (0) --- 29048 12:54:23 gettimeofday({1088247263, 401741}, NULL) = 0 29048 12:54:23 gettimeofday({1088247263, 402017}, NULL) = 0 29048 12:54:23 gettimeofday({1088247263, 402271}, NULL) = 0 29048 12:54:23 setitimer(ITIMER_REAL, {it_interval={0, 0}, it_value={0, 99470}}, NULL) = 0 29048 12:54:23 sigreturn() = ?
