Title:
Chromium browser triggers PAE kernel bug: "Corrupted page table at
address"
Status in Linux:
Fix Released
Status in linux package in Ubuntu:
Incomplete
Status in linux source package in Precise:
Confirmed
Bug description:
This bug has been reported upstream and addressed in Debian.
I found it while running the upstream kernel 3.6.0-030600rc6-generic,
but since it was fixed in 3.9, it almost certainly applies to the
stock Precise kernel as well. It's rare and not easy to reproduce, and
I can't use my system properly with the stock Precise kernel (USB
fails after suspend) so I can't really test that for you.
After running Chromium for some time, it may be killed by the kernel,
with the following error in the kernel logs/dmesg:
