Red Hat Bugzilla – Bug 69295
(BIOS)System Error 16 crash loading on Athlon SMP
Last modified: 2008-08-01 12:22:52 EDT
Description of Problem:
anaconda crashes at the end (or near end) of processing the first CD
on a dual Athlon SMP using a Sony 56X CD. The processors are the 2.2GHz
Athlon MPs with the 760MP chipset.
Version-Release number of selected component (if applicable):
Whatever ships with RH7.3
Steps to Reproduce:
1. installing on a clean machine from cdrom - use vanilla workstation config
2. observe unhandled exception from Python at about the point the system
asks for the 2nd cdrom.
3. abort the system load
crash, backtrace printout. System Error 16, Device of resource busy. No
system installed. From the backtrace it looks like they system was trying
to unmount the cdrom ...
No problems reported, system installed.
This is a showstopper in bringing the system up.

The RH support folks have decided that this is a real bug and not a cockpit
error and handed me off to you. What sort of response time can be
expected. I've provided a summary of the information provided the support
I browsed the bugzilla anaconda file. Several reports of this problem can
be found there. See 66224, 64422, 62416. Comments with at least one of
the bugs claim this to be a media problem!
A check of the /tmp/syslog file for the failed install showed no error
reports and nothing unexpected. There was no listing of anything after the
journalling file system(s) were enabled.
I checked the RH7.3 media with the mediacheck option. They passed.
In frustration, I tried a RH 7.2 install. It worked--that is, I did not
encounter the anaconda bug. Although I am at a loss to explain the
mechanism, perhaps media errors are the problem. (Support: What's the
procedure to get fast turnaround replacements? I need to get this
particular system up and running and stable.)
The RH support proposed a solution, performing the load with:
linux noathlon mem=nopentium pci=bioirq hdc=cdrom ide=noautotune
produces the same problematic results. The install fails and anaconda dies
in /usr/lib/anaconda/isys.py at line 171 in umount in the statment
rc = _isys.umount( what )
where the value of what is '/mnt/source', Remove_Dir (another parameter)
defaults to 1, and the failure is an unhandled exception, System Error
(16, 'Device or resource busy').
The hardware consists of a Tyan 2468 GN Dual Athlon MBD with the 760MP
chipset, 2 x Athlon 2100MP processors, 2 GB DDR Memory, IBM 7200 RPM
80GB IDE disk (primary master) and a 56x CDROM (secondary master).The BIOS
setting for the disk lage disk access mode is "Other" as opposed to "DOS".
Other BIOS settings are as factory designed.,
After several rounds with the RH Support folks, they identified an
undocumented flag for the boot linux, apic, which seems to have solved
the problem. I was able to install RH Linux 7.3 on the new machine and
configure things appropriately. Apparently, the source of the bug was a
Filing with kernel since its a piece of hardware they ought to know have problems.
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases,
and if you believe this bug is interesting to them, please report the problem in
