Summary: [2.5.69-bk14] Unable to handle kernel null pointer
Kernel Version: 2.5.69-bk14
Status: NEW
Severity: normal
Owner: jsimmons@infradead.org
Submitter: s.rivoir@gts.it
Distribution: Debian sid
Hardware Environment: HP Omnibook XE3l
Software Environment: kernel 2.5.69-bk14
Problem Description:
I get this everytime I run SVGATextMode with a resolution with more than 43
rows; I'm not sure that this failure it's a kernel bug, but I suppose it
should not give this error anyway...
Steps to reproduce:
# SVGATextMode "80x50x9"
<1>Unable to handle kernel NULL pointer dereference at virtual address
00000010
printing eip:
c01be43c
*pde = 00000000
