Description Jason Baron 2004-12-03 17:04:15 UTC
*** This bug has been split off bug 139571 ***

Jesse Barnes noted that cat'ing /proc/pal/cpu0/tr_info several times
led to a kernel hang.

As a result of the investigation it was noted that __pa was used where
ia64_tpa should have been used.

There has been a discussion on linux-ia64 which can be viewed here:

Do we know which versions of our kernels are affected by this issue? 
From an initial look, it would seem only 2.6, but obviously I'm not
the best person to answer that question.

Comment 1 Jason Baron 2004-12-03 17:05:36 UTC
this is an issue for RHEL3 as well...tracking bug

Comment 2 Jason Baron 2004-12-15 18:28:53 UTC
this actually isn't an issue for 2.4 based kernels, b/c the kernel is
identity mapped in region 7. closing.

Comment 3 Mark J. Cox 2004-12-15 18:39:44 UTC
Marcelo agrees; removing from tracking.
