Description Guy Streeter 2008-05-19 17:07:47 UTC 
An error in conditional compilation disabled /sys/devices/cpu/cpu*/topology/ in
the 2.6.25 kernel. This is a regression from Fedora 8.
Please consider carrying the upstream patch at
5c3a121d52b30a1e53cdaa802fa1965fcd243164 until the F9 kernel rebases to
2.6.26-rc2 or later. irqbalance, among other things, depends on the cpu topology
information.
Comment 1 Dave Jones 2008-05-19 17:29:58 UTC 
This is in 2.6.25.4, which the current cvs has updated to.
It'll be in an update soon.
Comment 2 Dave Jones 2008-05-19 18:08:00 UTC 
wait a second..
/sys/devices/cpu never existed. it's always been /sys/devices/system/cpu

and looking on 2.6.25-14.fc9.x86_64 I see /sys/devices/system/cpu/cpu*/topology/
just fine.  What's going on here?
Comment 3 Dave Jones 2008-05-19 18:09:04 UTC 
ah, this only affected 32 bit. never mind.
Comment 4 Guy Streeter 2008-05-19 18:53:33 UTC 
my bad. I should have said "on 32bit". I did set the Hardware to x86

and I typoed the /sys/devices/system/cpu/cpu*/topology/
Comment 5 Guy Streeter 2008-07-28 16:14:53 UTC 
This is fixed in the current F9 kernel.
