Dear developers and users,
I am trying to install kdb-v4.4-2.6.31-common-4.bz2
and kdb-v4.4-2.6.31-x86-4.bz2on 2.6.31.8 stock-kernel - the stock kernel is
patched and installed in Fedora 12running on an OPTIPLEX - 780 from DELL.
1. the patches are applied cleanly
2. configuration and compilation is done cleanly
3. when I try to use the pause from the USB-UHCI keyboard, the system freezes
4. so< i wrote a simple module that can just load and enter KDB using
KDB_ENTER()
5. when I did that in a uniprocess mode(maxcpus=1), the following oops
message was dumped. Please let me know, if there are any patches for
this particular problem.
Regards,
babu K =======================================================Hello, worldBUG:
