Description of problem:
After upgrading from redhat 6.2 to 7.2, the kernel was loading driver
ncr53c8xx.o to operate a symbios scsi controller. The system would some
times boot up ok, but most of the time it would crash during disk checking
after the kernel finished booting.
I then changed the /etc/modules.conf file and replaced the ncr53c8xx entry
to sym53c8xx and this fixed the problem. The initial redhat 6.2 chose the
ncr53c8xx and I guess this choice persisted through the upgrade to redhat
7.2. RedHat 7.2 should have chosen the right driver for the symbios scsi
controller and overwrote the /etc/modules.conf with the correct choise. The
odd thing is that the original kernel which gets installed with redhat 7.2,
2.4.7-10 seemed to work ok with the ncr53c8xx driver.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.get a system with a symbios scsi controller.
(i.e. an SGI 4100 linux system for example.)
2.install redhat 6.2
3.upgrade to redhat 7.2
You haven't stated which kernel it is that doesn't work.
I've got two machines with this SCSI card, sample from /proc/ioports -
fd00-fdff : Symbios Logic Inc. (formerly NCR) 53c810
fd00-fd7f : ncr53c8xx
These work fine with kernel 2.4.9-31, but a kernel panic occurs with kernel
2.4.9-34. I've tried going to RedHat 7.3, but this also is probably
misdetecting the cards.
I guess the solution is to manually change /etc/modules.conf for both servers,
but of course it would be better if anaconda detected them properly.
However, since these cards are so old now and off the hardware compatibility
list I wouldn't hold my breath for a fix.
And I won't even mention that these machines couldn't install X-windows with a
Mach 64 card, (bug 54134). Oops. I just did.
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
the bug tracker at: http://bugzilla.fedora.us/
