Description David A. Lethe 2001-05-21 16:37:29 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 4.0)

Description of problem:
The qla2x00 driver included with RH7.1 locks up when processing vendor-
unique SCSI writes. After examining source, it does NOT process the 
dxfer_direction component of the new SG (pass-through) structure 

The new qlogic driver at their ftp site works properly on the 2.4 kernel, 
and should be incorporated into future releases of the O/S.

How reproducible:

Steps to Reproduce:
1. send any vendor-unique write command using new SG device driver, and 
the I/O will never complete.  Of course this requires an external FC 
device capable of processing such commands as a RAID subsystem using a 
vendor-supplied in-band configurator.


Additional info:

The working device driver is at http://www.qlogic.com/bbs-
This driver works with 2.4 kernels, including IA64 architectures, as well 
as previous kernels.

This is the working driver

Comment 2 Arjan van de Ven 2001-05-21 16:44:17 UTC
Version 4.28 was added to our tree recently; I expect a kernel with this driver
to arrive in rawhide shortly.

Thanks for the bugreport.
