I tested 2.6.27.3 on Debian Sarge. I got the same result. So, I tried to produce different results. I pruned declaration of module_param(usbfs_snoop) like static int usbfs_snoop; /* module_param(usbfs_snoop, bool, S_IRUGO | S_IWUSR); MODULE_PARM_DESC(usbfs_snoop, "true to log all usbfs traffic"); */ and I got the below result. # ls -ail /sys/module/usbcore/parameters/ total 0 189 drwxr-xr-x 2 root root 0 Oct 24 2008 189 drwxr-xr-x 2 root root 0 Oct 24 2008 . 188 drwxr-xr-x 4 root root 0 Oct 24 2008 .. 190 -rw-r--r-- 1 root root 4096 Oct 24 2008 autosuspend 192 -r--r--r-- 1 root root 4096 Oct 24 2008 blinkenlights 193 -rw-r--r-- 1 root root 4096 Oct 24 2008 old_scheme_first This time, 'use_both_schemes' entry became no-name. I added declaration of module_param(usbfs_aaaaa) and module_param(usbfs_zzzzz) like static int usbfs_aaaaa; module_param(usbfs_aaaaa, bool, S_IRUGO | S_IWUSR); MODULE_PARM_DESC(usbfs_aaaaa, "true to log all usbfs traffic"); static int usbfs_snoop; module_param(usbfs_snoop, bool, S_IRUGO | S_IWUSR); MODULE_PARM_DESC(usbfs_snoop, "true to log all usbfs traffic"); static int usbfs_zzzzz; module_param(usbfs_zzzzz, bool, S_IRUGO | S_IWUSR); MODULE_PARM_DESC(usbfs_zzzzz, "true to log all usbfs traffic"); and I got the below result. # ls -ail /sys/module/usbcore/parameters/ total 0 189 drwxr-xr-x 2 root root 0 Oct 24 2008 189 drwxr-xr-x 2 root root 0 Oct 24 2008 . 188 drwxr-xr-x 4 root root 0 Oct 24 2008 .. 190 -rw-r--r-- 1 root root 4096 Oct 24 2008 autosuspend 192 -r--r--r-- 1 root root 4096 Oct 24 2008 blinkenlights 193 -rw-r--r-- 1 root root 4096 Oct 24 2008 old_scheme_first 195 -rw-r--r-- 1 root root 4096 Oct 24 2008 usbfs_aaaaa 196 -rw-r--r-- 1 root root 4096 Oct 24 2008 usbfs_snoop 194 -rw-r--r-- 1 root root 4096 Oct 24 2008 use_both_schemes This time, 'usbfs_zzzzz' entry became no-name.

It seems to me that somebody is overwriting (or truncating) at address of module_param(usbfs_snoop) . Is there a way to change the address of module_param() defined by usbcore module?
