After installing RH6.0 on a machine that had been happily running 5.1 for several months, I have run into a problem. Another user (rdnelson) reports a similar problem. Running with an off-the-shelf 6.0 kernel (2.2.5-15.i586) on an AMD K6-2/333 with 32M memory, the machine locked up with the following message in /var/log/messages: Oct 7 17:36:50 mercury kernel: Unable to handle kernel NULL pointer dereference at virtual address 00000004 For both of us, this problem seemed to occur while using Netscape Communicator. I have since upgraded to 2.2.5-22 and have not seen the problem again, but I don't know what web site/page I was looking at that caused the problem initially, or even if it was data-dependent. I have been unable to determine what changes occurred between release 15 and release 22, though the upgrade center indicates 22 fixes a potential for "remotely hanging the machine". Could someone verify whether this is a known or fixed problem?
We'd need more information. If you could run the full oops text through ksymoops, it would be helpful.
Does the 2.2.12 kernel from 6.1 still have this problem?
