The previous Ubuntu was 12.04 when Firefox worked fine. The computer is an HP Pavilion DV4 laptop and now is upgraded to Ubuntu 13.10, Firefox v28.0,Canonical-1.0. Firefox may run for sometime then suddenly a message that Firefox has crashed appears or the machine simply shows a black screen of death with terminal like output mentioning things like,
"kernel panic-not syncing:Fatal exchange in interrupt",Call trace:
with lines like
"smp_apic timer__interupt+Ox34/Ox3c" and
"?poll_select_copy remaining +Ox100/Ox100"
"Code: ( followed by multiple pairs of Hex values)" and
"Shutting down cpus with NMI"
"drm_kms_helper: panic occurred, switching back to text console.
A system's test pronounces the Harddrive, RAM memory, CPU and video drivers are fine. To recover the situation, I have to do a coldstart using the power button. On other occasions, Firefox and the cursor just freezes without the black screen of death but a cold restart is still required. Do I need to go back to version 12.04? Should I upgrade to version 14.04? I have done a crash report as sometimes the window says, module 'Xorg' is at fault but have gotten no reply. Any help appreciated.....
