VMware installs its own kernel modules into the running kernel. Red Hat does not support the usage of kernel modules supplied from external sources. Please let the VMware people know about this problem, so they can look into it, and hopefully fix it. I note that you're also using an Nvidia video card. If you are using Nvidia's closed source proprietary binary only video driver, Red Hat also does not support that, for the same reasons. If so, be sure to also inform Nvidia of the problem, in case it is related to their driver, so they can fix any problems their driver may be causing also. After living with this problem for some time now, it does not appear to be related to any specific application program. The last two times the system froze I was running only "gedit", krellm, and a terminal window. Just now, when attempting to write this update it froze again, without any apparent provocation. I have attached two files, one containing a list of running processes and the other, a list of loaded modules. It does appear that the NVida video driver is installed. These files are located in /usr/src/linux-2.4.9-13/drivers/video/riva: ==> accel.c <== Copyright 2000 Jindrich Makovicka, Ani Joshi ==> fbdev.c <== Copyright 1999-2000 Jeff Garzik ==> nv4ref.h <== Copyright 1993-1998 NVIDIA, Corporation. ==> nvreg.h <== Copyright 1996-1997 David J. McKay ==> riva_hw.c <== Copyright 1993-1999 NVIDIA, Corporation. ==> riva_hw.h <== Copyright 1993-1999 NVIDIA, Corporation. ==> riva_tbl.h <== Copyright 1993-1999 NVIDIA, Corporation. This is the default driver from the RedHat installation. If you think this could be the source of this lock up, please point me to where I can find a less troublesome driver. I don't think it's likely VMware is causing this. I've installed the newest 3.0 software and built drivers on this machine during the setup. Besides, I haven't heard of anyone else complaining of system freeze from VMware. Is it possible that my compiler is the problem? I'm using the compiler installed by default during the system installation with whatever updates have been available. While building the VMware modules, I got this warning: As of October 2001, Gcc 2.96 is not yet a supported compiler by the Linux kerneldevelopment team. Have a look at /usr/src/linux/Documentation/Changes to get thecorrect compiler installed. This script will take into consideration the CC environment variable. Do you want to go with gcc version 2.96 compiler ? If the problem is the compiler, why do we have a problematic compiler packaged with the 7.2 distribution? If the problem is the video driver, why do we have a problematic compiler installed by default? I would appreciate any information or recommendations you might offer. Thank you for your help! --Cal Webster Created attachment 37141 [details]

As I mentioned earlier, VMware is not supported by Red Hat Linux. What this means in a larger sense, is that, if one encounters a bug, system lockup, or similar, either while using VMware, after using VMware, or after any of the VMware kernel modules have even been loaded once, any problems encountered at all from that point on, are not supported by Red Hat. We also do not officially support installing Red Hat Linux into a VMware virtual machine. We encourage users experiencing bugs with external kernel modules having been used, to reconfigure their system to disable all external modules, reboot, and run their system in the default supplied configuration to reproduce the problem. This holds true for any external software providing its own kernel modules, or directly accessing hardware. >As of October 2001, Gcc 2.96 is not yet a supported compiler by >the Linux kernel development team.

Do you want to go with gcc version 2.96 >compiler ? The compiler supported and used officially by Red Hat Linux for all 7.x releases, is gcc 2.96, which has been used to compile _all_ of the Red Hat 2.4.x kernels, which subsequently pass intense cerberus testing, as well as other Quality Assurance testing before our kernels are released officially. The 2.2 series kernels in 7.0 were build with the older egcs due to kernel bugs (not compiler bugs). ftp.kernel.org shows the datestamp for the 2.4.10 kernel as: -rw-r--r-- 1 korg korg 22911818 Sep 23 18:30 linux-2.4.10.tar.bz2 Here is an excerpt from the linux/Documentation/Changes: The Red Hat gcc 2.96 compiler subtree can also be used to build this tree. You should ensure you use gcc-2.96-74 or later. gcc-2.96-54 will not build the kernel correctly. So, clearly the VMware statement is not accurate. Either way however, whatever compiler you use, or VMware recommends to use, is what you need to use to get support from VMware, using their technical support channels. Red Hat does not support VMware. The following document may also be of use for general gcc 2.96 information: http://www.bero.org/gcc296.html We absolutely are interested in knowing about bugs encountered in valid supported software configurations that do not include unsupported add on kernel modules. If you can reproduce this bug, as described above, without having loaded or used VMware from a fresh reboot, then we can look into this further, and encourage you to reopen the report, with any new updated info. Also, since VMware is involved, it would be a good idea to contact their technical support and/or bug tracker, to inform them of the problem as well and ensure that they can track any software bugs that may possibly be found in their product. Hope this helps. |
