Description of problem:

An unattended machine was at a kernel oops screen.  Though I could not get the console to switch to either a working console or to the X console, the system was still functional according to the logs.  After reset, the logs reveal:

Apr  4 23:40:55 matrix kernel: Fixing recursive fault but reboot is needed!


The system is using a USB wireless network adapter.  Whether that is related or not I do not know.  Sometimes it seems that during web browsing that I get too many time where I have to reload the page for it fully load.  The logs are full of this apparently since the adapter was installed:

Apr  4 23:41:02 matrix kernel: ===>rt_ioctl_giwscan. 5(5) BSS returned, data->length = 629

Oddly, the logs show subsequent normal activity following as though infrastructure is running fine except that I did not know how to get it back with Ctrl-Alt-F?.  msec, for example, ran its scan at 4:00 am.

Version-Release number of selected component (if applicable):
$ mgaapplet --version
Drakxtools version 13.58

How reproducible:
No idea.  The system was not in use at the time.  Possibly by accelerating update checks?  The system had an uptime of only 1.5 days due to a power outage.  Prior to that it had been up several days, so it is not something that happens every update check.

Steps to Reproduce:
