Does anyone happen to know the correct version of kgdb to use for debugging the 2.6.9 kernel? Version 2.4 is apparently for the 2.6.15 kernel, and version 2.2 is for the 2.6.13 kernel, but I've read all the way through the documentation and nowhere does it say which kgdb goes with which kernel. Thanks. -------------- next part ------------...

Hello! My attempt to build openoffice.org-3 seems to be hanging. Pressing Ctrl-T produces: load: 0.11 cmd: tcsh 79759 [sleeping without queue] 0.00u 0.00s 0% 0k (tcsh is used by OOo's build-script). What is this "sleeping without queue" state, and why is process in it for so long? This is an 4-CPU amd64 system with 4Gb of RAM. Only 16% of the swap is currently in use and

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm trying to connect the *same* serial device to two KVM Linux machines where one is running KGDB and the other uses the connected serial to interact with the target machine running under KGDB. However, I'm unable to do so. Using a pty port, I am able to use my kgdb setup with host/VM but unable to make it work with VM/VM since it's two different pty created on the two machines. Anyon...

Hello, Since FreeBSD 9.1 I have strange problems with the distribution. Some servers are rebooting without any kernel panic, instanly. First i thought it's a problem with my KVM system, but one of my FreeBSD under a Dell R210 have the same problem. The servers concerned are now: - Monitoring server - LDAP test server - Some other servers, randomly (not in production). First i thought it's
