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):
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
Actual Results: ctrl-c doesn't work
Expected Results: ctrl-c works
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
