linux-2.6.15-rc1 crashed my file system for 2.6.14

linux-2.6.15-rc1 crashed my file system for 2.6.14

[Lukas Ruf]

Dear all,

today, I tried linux-2.6.15-rc1 on my laptop (thinkpad t40p).
Before it had been running 2.6.14 without troubles.

What happened:

- compiled 2.6.15-rc1 with the 2.6.14 .config file.

- make install modules_install ; update-grub

- booted into 2.6.15-rc1

- started X.org (latest available in Debian unstable, DNR version)

- crashed the screen output -> rebooted

- booted in 2.6.14 (that run without problems)

- received the 'VFS ... cannot mount root ...' error message
  (ext2 and ext3 are statically compiled into the kernel)

- booted into Knoppix, fsck.ext3 didn't show any error

- retried 2.6.14 -- same error persists

- 2.6.15-rc1 boots still smoothly

- however, 2.6.15-rc1 has still no screen output after trying to
  start X.

---> how can I get back to 2.6.14 without loosing data

Any help is very welcome and urgently needed.

Thanks in advance,

wbr,
Lukas
