Bug Description
I have HP t5000 thin client. Everything works on Edubuntu 7.10 Classroom Server.
On Hardy Alternate Beta 8.04 it fails to boot. It flashes green screen and after that boot itself again.
Just before green screen flash t5000 says this: "memory size detection failed"
Here is Flash-movie about booting process:
http://
There is similar bug filed for MythTV:
"Summary: Both the kernel vt8623fb driver and the Xorg via driver should be changed to correctly determine the amount of video memory."
https:/
Best Regards Asmo Koskinen
===
SRU Justification
Justification: systems with the vt8623fb driver crash on boot if the vt8623fb driver is loaded
Impact: system crash
Fix Description: blacklist the vt8623fb driver in the framebuffer blacklist
Patch: http://
Risks: anyone specifically using this driver would have to unblacklist it, we normally blacklist these drivers by default this one is missing from the list
TEST CASE: see bug description

Hello,
after upgrading a mini-itx machine (VIA CLE266 chipset) from ubuntu 7.10 to 8.04 the machine began to freezing at boot time.
Before freezing, for a instant, the screen becomes green, then the display shuts down (out of sync error).
I figured out that it was the VIA framebuffer driver vt8623fb that messed the whole thing up. d/blacklist- framebuffer and got the machine working.
In fact, I added the row
blacklist vt8623fb
to /etc/modprobe.
Actually, the vt8623fb driver is loaded by both the 7.10's kernel (2.6.22) and the 8.04's one, but the latter just crashes;
so please add to the blacklisted framebuffer modules the vt8623fb module, or reassign this bug to the kernel package if you think that it is kernel's fault.
