Description Alex Williamson 2005-04-01 16:22:11 UTC
From Bugzilla Helper:

Description of problem:
ia64 needs an extra cache flush to ensure the icache is coherent when modules are loaded.  I'll attach a patch that explicitly flushes the icache.

Version-Release number of selected component (if applicable):
XFree86-4.3.0-78.EL

How reproducible:
Didn't try

Comment 3 Rohit Seth 2005-04-12 16:16:40 UTC
We are seeing this issue on systems in Intel.  Please raise the priroity of 
this issue to high.  This is must fix for EL3 U6 (A lot of our internal 
validation teams are dependent on this issue).

Comment 4 Mike A. Harris 2005-04-13 22:54:17 UTC
Thanks for the report, and the patch.

We have reviewed the issue and believe the patch is safe to apply.  We've
also confirmed that this patch has already been integrated into X.Org CVS
HEAD, and is being considered as a candidate for the 6.8.x stable branch
tree as well, so we've approved it for inclusion in RHEL3 U6 also.

Once U5 has been released, and our CVS tree is unfrozen, we will
incorporate the fix into RHEL3 and build new packages in the
RHEL3 U6 tree.  When new rpm packages are built, we'll make packages
available to you for testing, and update the status here.

Thanks again.



Comment 7 Mike A. Harris 2005-05-19 19:05:59 UTC
Status update:

The patch for this issue is in our queue to be included in RHEL U6.  Once
RHEL U6 is finalized and we're certain no further rebuilds will be required
for U6, we will be opening our CVS tree for U6, and the changes will be
committed to CVS at that time.  We will also provide updated rpm packages
at that time, and update the status of this report.

Thanks.

Correction - the last comment should have read:
