Description adi 2001-10-02 19:52:44 UTC

From Bugzilla Helper:
User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.2-2 i586)

Description of problem:
Installing the kernel module 'ppa' on an SMP kernel locks the system
completely. (driver file /lib/modules/2.2.19-6.2.7smp/scsi/ppa.o)

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


How reproducible:
Always

Steps to Reproduce:
1. Boot an SMP kernel (I tried with all the 6.2 smp kernels: 2.2.19-6.2.7,
2.2.19-6.2.1, 2.2.17-14, 2.2.16-3)
2. 'insmod ppa' or 'modprobe ppa'
3. watch your system lock up


Actual Results:  System locked and no keyboard or network activity was
accepted.  In other words, the machine transformed itself into an expensive
power consuming paperweight.

Expected Results:  Detect parallel port zip drive and continue operating
normally.  Works fine with non-SMP 6.2 kernels.

Additional info:

Hardware:

 - Supermicro P6DBE motherboard
 - dual Pentium III 550Mhz (Katmai) processors, 512K cache each
 - 256M memory
 - standard iomega zip100 parallel port drive

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
persists.

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/
