Description Tom Haynes 2002-12-26 19:26:22 UTC
Description of problem:
running Compaq Proliant 5000 mdl 1x (1 cpu 200mhz Ppro, 128m ram, 2 eth using 
TLAN driver, embded fast-wide scsi2 controller,sd0 4.2gb,sd1 4.2gb,sd2 
4.2gb,sd3 4.2gb,sd5 CDROM,fd0 1.44mb)
Booted from floppy (bootnet.img from 8.0 cd) with command
   linux mem=exactmap mem=640K@0 mem=127M@1M
loaded TLAN.O driver (from drvnet.img) for 2 ethernet adapters (compaq net/flex 
and nettelligent)
network connection completed succesfully
ALT-F4 log read...
<4>TLAN: eth0: Link active
<6>spurious APIC interrupt on CPU#0, should never happen.
<6>spurious APIC interrupt on CPU#0, should never happen.
boot continued fine
When I could not mount the NFS image I tried to ping the computer I was 
installing linux on to make sure the link was good. for every ping sent to the 
computer a new line was added that said the same thing...
<6>spurious APIC interrupt on CPU#0, should never happen.
except for once when it said...
<4>spurious 8259A interrupt: IRQ7
IRQ 7 is for the ethernet card I have active
Have not completed install at this time (not related problem) to see if it 
hapen during runtime.

Version-Release number of selected component (if applicable):


How reproducible:
<6>spurious APIC... With 58 of 100 consecutive pings
<4>spurious 8259A... Only once (none during 100 pings)

Steps to Reproduce:
1.load TLAN module
2.ping IP address from remote station

    
Actual results:
sent 100 pings
58 resulted in <6>spurious APIC...

Expected results:
no output or <4>spurious 8259A...

could you try adding "apic" to your "mem=" line ?

Comment 2 Tom Haynes 2002-12-29 05:06:42 UTC
I did get 7.1 to install. The main bug seemed to be a problem with the CD. 
However, I did a new install of 8.0 and could not get X to work, either from 
the install or after configuration from the shell. my CL-GD5420/512 worked with 
7.1 but would not work with 8.0. I used LORES and "RESOLUTION=..." commands. 
Xf86Config could not get X to work either. But, that is a different bug.

Comment 3 Alan Cox 2003-06-09 13:37:55 UTC
As of Red Hat 9 we dropped single processor APIC support as it causes problems
(like the one here). This should have solved it.
