--- Begin Message --- Hi Yinghai,
When I boot with "disable_mtrr_trim mem=4g", the system boots fine.
Then I changed that to
"disable_mtrr_trim mem=6g" and a kernel panic occurs:
[...] Freeing unused kernel memory: 296k freed
[...] Write protecting the kernel text: 3040k
[...] Write protecting the kernel read-only data: 1352k
[...] khelper used greatest stack depth: 6724 byytes left
[...] Kernel panic - not syncing: No init found. Try passing init=
option to kernel.
I can always reproduce this: all it takes it to boot from a rescue CD,
switch between "mem=4g" and "mem=6g" in /etc/lilo.conf, run lilo and
reboot. If it is 4g, it boots fine; if it is 6g, a kernel panic
occurs. No other changes at all were made.
Same thing (kernel panic) occurs if mem=5g is used.
I am attaching the kernel config used when this happens.
Please let me know how I can help fix this. Does it somehow depend on
all those MTRR/etc memory-related options in the kernel configuration?
Thank you so much,
James
