2.6.17-rc6 for_each_online_cpu

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi

1)
The use of  for_each_online_cpu  in mm/slab.c causes great distress
for a SMP box,  replacing with for_each_online_node  " is better "

2)
The rewrite of drivers/serial/sunzilog.c hammers the sun4d pretty
hard, it doesn't walk the "zs" nodes correctly.  What I have as a
patch now misses 2 of 12 serial ports, I'll send once that improves.

3)
This one pops up in the middles somewhere,

BUG: spinlock bad magic on CPU#0, swapper/1                                     
 lock: f0f00800, .magic: 00000000, .owner: <none>/-1, .owner_cpu: 0             

not sure if the truncated next line is part of it or not.

4)
Then I stumble again at the end ....

EXT2-fs error (device sdc3): ext2_check_page: bad entry in directory
#2: unalig0

(yes it's truncated on the serial console)


Suggestions welcome :)


Thanx
  Ray
