Folks, I recently bought my first PC, however, I've been working with Unix for many years so this is not a newbe situation. Since I got it I have had nothing but strange problems with it which I so far been unable to determine whether they are hardware problems or software. I have run diagnostics on the hardware and I've brought the system back once already and there doesn't seem to be any obvious hardware problems, but yet the system will not stay up more that 24 hours. First I'll describe the hardware then I'll list the various problems I've encountered.
Motherboard: ASUS Dual Pentium II (350Mhz) w/ on board SCSI 1 4.3 GB disk 1 9 GB disk 1 5.1 IDE disk Matrox G200 video card Ensoniq AudioPCI sound card Eexpress pro 100 Ethernet card
I have RH5.2 + 2.1.130 kernel loaded on the IDE drive.
Here are the problems I see in no particular order.
1) When I build the kernel it takes about 10 - 20 tries to get it to build. This is due to the compiler terminating with sigsegv or other error. I'm using the gcc-2.7.2.3-14 compiler.
2) I will run make and make will lock up, i.e. it becomes an unkillable process, and my only resort is to shutdown and reboot the box. This problem looks like a traditional deadlock scenario. The wait channel field in the ps output always shows end as the address it is waiting on.
3) The system will lockup. This occurs even if the system has been idle. It will be working when I go to bed, and be locked up in the morning. By locked up I mean no keyboard or mouse input works for my X session, and any attempt to ping or telnet from another box fails. Sometimes ping will work, but not telnet. Obviously switching to an alternate console fails. This has occured whether or not I am running xscreensaver.
4) Various processes will terminate with sigsegv while running. e.g. xterm's will simply go away, or I'll be logged off my xsession completely.
5) At various times during the boot sequence I will get various oops regarding either NULL pointer dereference or problems accessing various virtual addresses.
6) On at least 2 occasions CPU 1 has panic'd with the following:
Attempted to kill the idle task!
7) I'm getting lots of messages of the form:
schedule_timeout: wrong timeout value <some val> from <some ptr>
in /var/log/messages
My question is has anyone had any success running an ASUS dual pentium motherboard along with a Matrox G200 video card ( using the matrox X server from SuSe)?
If not, does anyone have a suggestion as to how I can best debug these problems, or better yet does anyone have fixes :-)?
Any thoughts would be appreciated.
