Public bug reported:
What follows are my recollection of events resulting in my Samsung
900x4C no longer POSTing after updates.
I was running an outdated Quantal install (of a few weeks old) and
recently applied Quantal updates to bring my laptop up to date. One of
the updates included the linux-image-3.5.0-17 kernel. After updating and
rebooting my laptop would kernel panic shortly after the grub menu
displayed. I attempted to use any of the previous kernels listed and
similar kernel panics occurred.
I managed to boot into a USB installation environment, mounted my
laptop's primary partitions, chrooted in and reinstalled the linux-
image-3.5.0-17 kernel package. The laptop would then boot, however I
noticed that wifi was not working. I then discovered that the linux-
image-extra-3.5.0-17-generic package had been removed taking the wifi
drivers along with it. I plugged in a ethernet cable and reinstalled the
linux-image-extra-3.5.0-17-generic package. After rebooting to ensure
that the wifi drivers would load correctly and that the kernel would no
longer panic, I found that the machine would not longer POST at all.
Pressing the power button turns on the blue power LED, but nothing
further happens. It seems that the laptop has been bricked. I cannot
remove the laptop's battery and so I am currently running the laptop
without power attached to attempt to run down the battery.
I had UEFI enabled in the BIOS and the last kernel which seemed to work
for me was linux-image-3.5.0-15 (although I cannot confirm).
This seems very similar to Bug:1040557 which also bricked other models
of Samsung laptops.
For obvious reasons, I cannot reproduce nor provide logs. If there is
any additional information I can provide, please let me know?
