ok, further details :-)

running kernel 2.6.27-0.186.rc0.git15.fc10.i686, on a thinkpad T40 :

[root@rawhide ~]# cat /proc/mounts 
cat: /proc/mounts: Invalid argument
[root@rawhide ~]# strace cat /proc/mounts 
open("/proc/mounts", O_RDONLY|O_LARGEFILE) = 3
fstat64(3, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
read(3, 0x8515000, 1024)                = -1 EINVAL (Invalid argument)
[root@rawhide ~]# mount
/dev/sda3 on / type ext3 (rw)
none on /proc type proc (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/sda2 on /boot type ext3 (rw)
none on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)

and there is no error message in the logs.

Comment 4 Dave Jones 2008-08-01 15:19:44 EDT
can you repeat this with todays -rc1 kernel ?
Can't find a way to reproduce this locally, so it's possible this got fixed
already upstream.
Comment 5 Fabrice Bellet 2008-09-16 16:54:27 EDT
it's fixed with kernel 2.6.27-0.323.rc6.fc10.i686, thanks!
