While running sensors (lm_sensors) on a via686* and rebuilding the kernel SRPM, this error was thrown to the console. The comments within the sources make it seem non-fatal and having once-in-a-long-while frequency, but I hit it with < 15 mins. uptime. I then halted the both programs and restarted them. A third vc that I was logged into would no longer start programs and although init caught my ctrl-alt-del and started sending TERM signals, CROND ran its 10 minute jobs twice before I finally cut power. I saw similiar behavior once during the beta while doing the same thing, but I was away for hours while this was left running and could not check the logs. Reproducible: Sometimes Steps to Reproduce: 1. Run a CPU intensive task (suggest "while true ; do rpm --rebuild --clean kernel.src.rpm ; done") 2. Run 'watch sensors|tail' at the same time 3. Wait. Actual Results: Ocassional hard lockups. Expected Results: Frequent hard lockups.

The machine runs fine if you don't have the lmsensors module loaded ?
No, I haven't been able to reproduce that exact error. I ran into the following two errors while trying to reproduce it, but I suspect a partially hardware related cause at this point.

Closing. Seems to match the VIA chipset flaw that 2.4.9 and later work around. If it stil occurs feel free to re-open
