[RESOLVED] Syslinux and kernel 3.2.8 update = unable to boot

I think it is after 3.2.8 update or some other updates from yesterday to today that break my system.
After update, I can't boot my system using normal kernel, it gives me the error:

invalid or corrupt kernel image

I can still boot using 3.0.22 lts kernel.

I am using BTRFS as root file system.

After logging in using 3.0.22, I reinstall kernel again, reboot. Same issue. Downloadgrade to 3.2.7, same issue. Reupgrade to 3.2.8, I got the follow:

initramfs unpacking failed: jumk in compressed archive
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block (0,0)
Pid: 1 comm: swapper/0 Not tainted
Call trace:
panic
mount_block_root
name_todev_t
....
start_kernel
gs_change

Try to upgrade again. I still got this error:

invalid or corrupt kernel image

Anyone encounter the same issue?

Is btrfs mounted with compress? Mount it without, then reinstall the kernel.

No, I don't use compress in btrfs.

Oh, hello.
With love from:

syslinux 4.05-1
linux  3.2.8-1

/boot mounted as ext2
/     mounted as ext4

Perhaps you should try rebuilding your image with mkinitcpio -p linux?

Did mkinitcpio -p linux tens of times. Change compress method to gzip, lzma, bzip2. None of them works.
My /boot is mounted as:
mount /dev/sda1 on /boot type btrfs rw noatime,ssd, discard

Hmm, well I guess this what they mean when they say BTRFS is experimental.

edit: Why on earth would you use btrfs for /boot?

I don't think it is BTRFS's problem. kernel 3.0.22 works. 3.2.7 was working yesterday. I think it is related to mkinitcpio that generate a bad image or syslinux issue.

btrfs on /boot should work directly in syslinux and grub2

The problem is though, mkinitcpio works perfectly fine for myself.
What I find interesting is this:

VFS: Unable to mount root fs on unknown-block (0,0)

Although you can downgrade and it works fine?

No it doesn't. Downgrade to version:
3.2.7, 3.2.6,  3.1.9

None of them works.

I suspect if I run mkinitcpio -p linux-lts, the LTS kernel will stop working.

Or, perhaps that block has become corrupted with the lack of a fsck for btrfs?
Otherwise I have no idea. But since I'm interested in btrfs, I'll follow this thread and see where it goes.

Good luck dude

The block is not broken. I generate a 3.0.22 image called my30.img (Another file). I got the kernel panic:

Initramfs unpacking failed: junk in compressed archive
