From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686 (x86_64); en-US; rv:1.7.12) Gecko/20051215 Galeon/2.0.0 Description of problem: I rebooted and booted into kernel-2.6.15-1.1871_FC5. I found in gnome-terminal, xterm, and on the console that ctrl-c and ctrl-z didn't always work. It would work at first. Then I would run something like ls | less, press q for quit, and then ctrl-c wouldn't work anymore. I have reverted back to kernel-2.6.15-1.1865_FC5, and it seems to work just fine. Version-Release number of selected component (if applicable): kernel-2.6.15-1.1871_FC5 How reproducible: Always Steps to Reproduce: 1. Install kernel-2.6.15-1.1871_FC5 2. Reboot into kernel-2.6.15-1.1871_FC5 3. Login to the console 4. ctrl-c repeatedly 5. ls | less 6. q 7. ctrl-c Actual Results: ctrl-c doesn't work Expected Results: ctrl-c works Additional info:
kernel-2.6.15-1.1878_FC5 contains the bug too
kernel-2.6.15-1.1881_FC5.x86_64 contains the bug also
kernel-2.6.15-1.1907_FC5 contains the bug I have isolated the problem further. If bash is set as the shell for the user then the problem goes away. kernel-2.6.15-1.1865_FC5 + bash = good kernel-2.6.15-1.1865_FC5 + zsh = good kernel-2.6.15-1.1907_FC5 + bash = good kernel-2.6.15-1.1907_FC5 + zsh = bad kernel-2.6.15-1.1907_FC5 + zsh + bash = bad I am going to try newer versions of zsh to see if the problem goes away.
kernel-2.6.15-1.1948_FC5 seems to fix it, it might have been an eariler kernel though.
