Title:
Installer creates no BIOS boot partition on UEFI system, system
becomes unbootable after automatic update
To manage notifications about
Public bug reported:
A clean install of Natty on a UEFI (ASUS P8P67) system gives me this
layout:
$ sudo parted /dev/sda print
Model: ATA Corsair CSSD-F12 (scsi)
Disk /dev/sda: 120GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 17
I now understand what happened. The installer creates (by default) an EFI
install, with grub-efi-amd64. The automatic update replaces grub-efi with
grub-pc, and the latter doesn't work. I manually reinstalled grub-efi and
everything works now.
But something is clearly wrong: an automatic update
This is also in the attached file, but to make it more obvious, here is
the partition table created by the installer:
$ sudo parted /dev/sda print
Model: ATA Corsair CSSD-F12 (scsi)
Disk /dev/sda: 120GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt

Public bug reported:
Did a clean install of Natty on a new 120G SSD. No dual boot, no custom
partitions -- I let the installer partition it as it wants. The system
installed and worked fine until the last grub update, at which point it
became unbootable ("invalid arch independent ELF magic" + resc
I haven't been able to reproduce the bug since replacing my graphics
card with a different model. It seems likely that the root cause was
hardware degradation, although I can't tell with certainty.

Worse than before. Screen corruption starts happening immediately on
login (in fact, even before -- on the login screen). What's more: in
Jaunty, corruption was extremely rare with DRI turned off (I've seen it
once in 1-2 months of use). Now even with DRI off, I see screen
corruption after several

No improvement. X freezes within a minute of login, and I couldn't even
get it to work long enough to take a screenshot for bug 391439 until I
used command line instead of the desktop menu. Attaching Xorg.0.log and
dmesg output.

After a while (usually a day or two), entire areas of the screen start filling
up with flickering lines.

https://bugzilla.redhat.com/show_bug.cgi?id=462157 seems to be the same
bug in Fedora. From the comments I gather that the jury is still out on
whether it's an Xorg bug or a kernel bug. It also seems like it's
currently closed, but never got fixed, which isn't encouraging.

Xorg randomly free
In my case it was happening in Intrepid, too. The difference is that in
Intrepid, X would almost always lock up without increased CPU
consumption, while in Jaunty it almost always locks up with 100+% CPU
usage.

X indeed freezes: no window updates, no response to mouse events (except
that the cursor moves), no response to keyboard events (Caps Lock
