Kernel version is 2.4.22 and I applied uml patch 2.4.22-6 to it. Root file System is the Debian-3.0r0.ext2.bz2 image from uml home page. # ls -l root_fs -rw-r--r-- 1 root root 62862336 Dec 14 18:06 root_fs # ./linux ubd0=root_fs debug gdb-pid=2646 >From debugger, failure happens here: Breakpoint 3, do_kern_mount (fstype=0xa194b000 "ext2", flags=32769, name=0xa1949000 "/dev/root", data=0x0) at super.c:793 (gdb) get_sb_bdev (fs_type=0xa01fb930, flags=-12, dev_name=0xa1949000 "/dev/root", data=0x0) at super.c:669 this call in get_sb_nodev fails: error = path_lookup(dev_name, LOOKUP_FOLLOW|LOOKUP_POSITIVE, &nd); with err code of ENOENT. Any ideas what's wrong or how I can debug this ? (I have tried the root=/dev/ubd/0 option - same result) thanks, Joydeep __________________________________ Do you Yahoo!? New Yahoo!
