Next when you get the state you can request the system "/usr/src/linux/Documentation/sysrq.txt", I mean you can print out the active processes and the kernel log buffer. Afterwards send the logs right back to the list, maybe we can then help further. > I’m thinking that there may be some hardware issues, but the thing was > running fine for 1 month, and didn’t do much beside yum update on it. > If you think of a hardware issue, you should run memcheck.
