Also a macbook.
Comment 3 Jurgen Kramer 2006-07-23 06:47:06 EDT
lockdep issue is still there with 2.6.17-1.2432.fc6
Comment 4 Jurgen Kramer 2006-07-23 11:17:32 EDT
Unfortunately still there with 2.6.17-1.2437 as well.
Comment 5 cq92j9y+rlkr0w 2006-07-24 02:28:33 EDT
I'm getting the same error with kernel 2.6.17-1.2437. I'm *not* using a mac.
Comment 6 cq92j9y+rlkr0w 2006-07-25 00:19:54 EDT
still there with 2.6.17-1.2439.fc6
Comment 7 Jurgen Kramer 2006-07-28 13:26:28 EDT
2.6.17-1.2462.fc6, still there. As is the cpufreq lockdep problem as discussed
on LKML.

I'm seeing this too with 2.6.17-1.2462.fc6. This is a HP Compaq nc4010 laptop.
Comment 9 Jurgen Kramer 2006-08-02 15:06:40 EDT
Should this bug be fixed with 2.6.17-1.2505.fc6? (there are lockdep fixes in
this version).

Comment 11 Dave Jones 2006-08-10 20:33:51 EDT
*** Bug 202055 has been marked as a duplicate of this bug. ***
Comment 12 Arjan van de Ven 2006-08-10 21:46:37 EDT
this should have been fixed in 2.6.18-rc4
not shure which rawhide version number corresponds to that
Comment 13 Dave Jones 2006-08-11 01:32:36 EDT
2.6.17-1.2517.fc6 which is the newest kernel reported above was rc3 based, so
this should be fixed in current builds.
 
Comment 14 Jurgen Kramer 2006-08-11 03:41:37 EDT
No so fast! The bug is still there with 2.6.17-1.2543.fc6
