I can get the system booted enough to work on (and totaly up) with this
partition failing. I dont know what more information from fdisk I can give
you, sda9 is there with .10, and gone with .11 It even allowed me to add a
new partition (i didnt save) I tried sfdisk but it gave me these errors.

sfdisk /dev/sda -O /tmp/foo
Checking that no-one is using this disk right now ...
BLKRRPART: Device or resource busy

This disk is currently in use - repartitioning is probably a bad idea.
Umount all file systems, and swapoff all swap partitions on this disk.
Use the --no-reread flag to suppress this check.
Use the --force flag to overrule all checks.

I didnt try the flags, Im worried that its going to overwrite my
filesystem. Heres my /proc/scsi/sym53c8xx/0 in case its needed. My system
is entirely scsi, except for an atapi burner. All scsi compiled static.

General information:
Chip sym53c875, device id 0xf, revision id 0x26
On PCI bus 0, device 16, function 0, IRQ 9
Synchronous period factor 12, max commands per lun 32

Whats my next step?
