2.6.25-rc2 + smartd = hang
Hi, Trying out 2.6.25-rc2 smartd always causes my box to hang. I can switch vt:s and the keyboard seems to work. Using sysrq-e I noticed a callpath open -> ext3 -> journals -> sync_buffer -> io_scheduel -> generic_unplig_device. I'd guess the open stems from smartd. Removing smartd from the startup, I'm now using rc2 fine... I got a nice jpg showing it as well. Known issue? /A -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

romfs as initrd
Running 2.4.0-test10 I try to get an romfs image to work as an initrd
image. It does work when mount `normally` using `mount -o loop`.
However, when used as initrd image it fails. Here's the relevant part
of dmesg:
RAMDISK driver initialized: 16 RAM disks of 16384K size 1024 blocksize
loop: enabling 64 loop devices
RAMDISK: romfs filesystem found at block 0
RAMDISK: Loading 3183 blocks [1 disk]
into ram disk... done.Freeing initrd
memory: 3184k freed
...
devfs: v0.102 (2622) Richard Gooch ([EMAIL PROTECTED])

Trying fs: ext2
Trying fs: cramfs
wrong magic
Trying fs: romfs
ROMFS DEBUG: rsb_word0 0 rsb_word1 0 sz 0
Kernel panic: VFS: Unable to mount root fs on 01:00
Where the ROMFS DEBUG message comes for this section of romfs/inode.c:
if (rsb->word0 != ROMSB_WORD0 || rsb->word1 != ROMSB_WORD1
|| sz < ROMFH_SIZE) {
if (!silent)
printk ("VFS: Can't find a romfs filesystem on
dev "
"%s.\n", kdevname(dev));
printk ("ROMFS DEBUG: rsb_word0 %i rsb_word1 %i sz
%i\n",rsb->word0,rsb->word1,sz);
goto out;
Not knowing that much about fs (and VFS) internals it seems that the
image is identified by the initrd code, but currupted/misplaced so it
cannot be used by the VFS when trying to mount it. I have no ideas what
steps are supposed to happen in between these two.
Help and insights appreciated.

/ on ramfs, possible?
I want my / to be a ramfs filesystem. I intend to populate it from an initrd image, and then remount / as the ramfs filesystem. Is that at all possible? The way I see it the kernel requires / on a device (major,minor) or nfs. Am I out of luck using ramfs as /? If it's easy to fix, how do I fix it? /Anders PGP signature

sync & asyck i/o
According to the man page for fsync it copies in-core data to disk prior to its return. Does that take async i/o to the media in account? I.e. does it wait for completion of the async i/o to the disk? /Anders PGP signature
