Description Yu Wang 2004-06-23 18:02:51 UTC
Under non-root account, after few minutes browsing websites with rich contents,
system hang. The problem remains until I disabled MTRR Support in kernel
configuration, since I found the following message in /var/log/kern.log:

"mtrr: 0x80800000,0x200000 overlaps existing 0x80800000,0x100000"

But the system goes slow after MTRR is disabled.

This had never happened for kernel 2.6.5 and below. Nothing have changed after
the kernel upgrade to 2.6.7.

Reproducible: Always
Steps to Reproduce:
With MTRR Support enabled, go into X and run Firefox, Evolution or Gaim or other software require large amount of memory. Keep playing around with these programs.
Actual Results:  
System hang
Mouse doesn't move
Can't ping through from other host.
Everything is dead

Expected Results:  
Everything alive.

Comment 5 Yu Wang 2004-06-24 13:38:21 UTC
emerge --info is provided. Now re-opened.
Comment 6 Greg Kroah-Hartman (RETIRED) gentoo-dev 2004-06-30 14:42:48 UTC
Does this happen with a stock kernel.org 2.6.7 kernel?
Comment 7 Yu Wang 2004-06-30 14:55:09 UTC
Yes, it happens with all the 2.6.7 kernel I've tried.
Comment 8 Greg Kroah-Hartman (RETIRED) gentoo-dev 2004-06-30 15:15:49 UTC
Then it's not a gentoo specific bug.

Please open this up at bugzilla.kernel.org, nothing we can do here.

thanks.
