Kernel 2.4.10 /proc/partitions

Kernel 2.4.10 /proc/partitions

[Andre Margis]

I'm testing Linux Kernel 2.4.10. I have a Dell 8450 with 8xP-III 700Mhz, 
10GBytes RAM, with megaraid PERC 3/DC. I have one logic disk (sda) with 4 
partitions (sd1, sd2, sd3, sd4). After boot, my /proc/partitions has this 
values:



 major minor  #blocks  name

   8     0   17692672 sda
   8     1      32098 sda1
   8     2      32130 sda2
   8     3    4096575 sda3
   8     4   13526730 sda4
   8     0   17692672 sda
   8     1      32098 sda1
   8     2      32130 sda2
   8     3    4096575 sda3
   8     4   13526730 sda4
   8     0   17692672 sda
   8     1      32098 sda1
   8     2      32130 sda2
   8     3    4096575 sda3
   8     4   13526730 sda4
   8     0   17692672 sda
   8     1      32098 sda1
   8     2      32130 sda2
   8     3    4096575 sda3
   8     4   13526730 sda4

the cat command never stop to list.



What's happen?




Thank's

I also have this problem as mentioned before.

The problem cropped up between 2.4.10-pre5 and 2.4.10-pre6, 
I did some checking. pre5 is fine, pre6 is broken.

>From what I saw, my guess is that
genhd.c and the gendisk rewrites might be related.

Unfortunately have no time to look at it until mid-October-
any help appreciated. 

cheers

I used to observe similar problem many kernels ago (2.1.x ?).
Then it was related to a module not removing its gendisk from the
list when unloading. The list became circular at its next modification.

Maybe something similar ?
