* 2.4.10 kernel Oops with compressed ramdisk

Greetings,

When attempting to load a compressed ramdisk from a floppy, the kernel
has a NULL pointer dereference.  The problem occurs inside of
rd_load_image().  rd_load_image() -> identify_ramdisk_image() ->
do_generic_file_read() -> update_atime() is the call trace.
inode->i_sb is not being set somewhere and the macro IS_NOATIME attempts
to dereference it.

#define IS_NOATIME(inode)   (__IS_FLG(inode, MS_NOATIME) || ((inode)->i_flags & S_NOATIME))

#define __IS_FLG(inode,flg) ((inode)->i_sb->s_flags & (flg))

Any ideas where inode->i_sb should be set?

I testing DELL 8450 under Linux, and kernel probe only two LUN's from EMC, 0 
and 1, but I have 2 and 254, if  I use scsi add-single-device to this other 
LUN's, works perfect. I try to set max_scsi_luns, has the same results.

I test with kernel 2.4.9, 2.4.10-ac7, both have the same problem.

With Conectiva Linux Kernel 2.4.5-9cl, he show all LUNS, work fine!

Any Help?


Thank's




Andre
