Description David Searles 2000-11-20 18:39:05 UTC 
Solid kernel panic on Dell OptiPlex GMT5100 (100 MHz Pentium w/ 64MB RAM; 
2 2.1 GB IDE disks; NEC SCSI CD-ROM on Adaptec controller; D-Link DFE-
530TX NIC) on which RedHat 5.2, Mandrake 6.0 and RedHat 6.1 ran great. 
This is a fresh 7.0 install with all applicable updates (as of 11/17/00) 
installed. When system is in use, all appears to be fine; when it sits 
idle, however, it crashes after varying amounts of time.
Crash data from console is:

Unable to handle kernel paging request at virtual address 40039c12
current->tss.cr3 = 00101000, %cr3 = 00101000

So what's the deal here. Does this bug stay NEW forever? Is this the "ignore it 
and maybe it'll go away" philosophy?

I am receiving a similar kernel panic with RedHat 6.2 kernel 2.2.16-3.  We are
running a cluster of 
Linux machines with MPI.  At least once a weak one machine will lock up and I
receive the following error:
Code: 8b 4a 04 85 c9 74 26 8b 5a 18 8b 02 89 01 8b 09 85 c9 74 0c
Aiee, killing interrupt handler
Kernel Panic:  Attempted to  kill the idle task!
In interrupt: handler not syncing.

Without running this oops through ksymoops _on your machine_, this information
is useless to us.
You can do that by doing
cat <file with the panic> | ksymoops
or if the system survived the oops:
dmesg | ksymoops
Comment 5 David Searles 2001-05-02 11:15:42 UTC 
I upgraded to RedHat 7.1 and this problem has disappeared, therefore please 
close this record. BTW, RH 7.1 seems VERY solid (a VERY welcome improvement 
over RH 7.0 which was flaky at best)
