Red Hat Bugzilla – Bug 30170
Full-Table-Mapped APIC mode causes a problem with installing Kernel Linux version 2.4.1-0.1.9smp or later.

SUGGESTED PRIORITY: HIGH
SmartStart v4.90, v.4.91, v.5.00
Red Hat Linux v7.1E
Kernel Linux version 2.4.1-0.1.9smp
HW CONFIGURATION (Just a case)
CPU=======>1GHz * 2
Sys Rom===>P21 01/11/01
HDD=======>18.2 * 1
Primary===>Wide U2 SCSI
STEP TO RECREATE THE PROBLEM:
1) Select manual path and Linux OS in SmartStart.
2) Go through System Configuration and other steps needed.
3) Complete SmartStart interview and launch OS installation.
4) Server fails to boot up after finishing entire installation.
PROBLEM DESCRIPTION: System Configuration Utility selects Full-table
mapped APIC table when it recognizes multi-processor installed in its
hardware. Then, its kernel 2.4.1-0.1.9smp fails installation and comes
into a stuck while booting up. The boot console repeats timeout logs.
SCSI host 0 abort (pid 0) timed out - resetting
SCSI bus is being reset for 0 channel 0.
Sym53c8xx_reset: pid=0 reset_flags=2 serial_number=1
I'm happy finally report that we have found a fix for this issue. A patch
from Alan Cox (one of the kernel popes) was just released (2.4.2. kernel -
Alan Cox patch 5 is the version we tested in the lab). This patch appears
to have fixed the problems that were encountered when installing the
newest kernel on a ROC-enabled system (e.g. DL360 & DL380). Using a DL380
with ROC installed, we patched the 2.4 kernel with Alan Cox's latest patch
and it successfully loaded in Full Table Mapped mode. This, of course,
concludes that there is a problem with the kernel and all of the
distributions will need to be notified accordingly. We can't say "exactly"
(meaning specific lines of code) what in Alan Cox's patch fixes this
problem at this time, but I'm sure each distribution has their own ways of
fixing the affected files. We do know that it has to do with the files
pertaining to APIC.
We already resolved this bug working with you a few days ago.

The following SCSI issues should prove to be dependent upon the APIC fix found
in Linux Kernel 2.4.2-patch5. These SCSI issues are being tested at this time,
now that the latest beta seems to have the needed patch.
