Title:
[Lenovo ThinkPad T520 4240] won't boot with 3.5.0-27
Status in “linux” package in Ubuntu:
Invalid
Bug description:
After updating to kernel linux-image-3.5.0-27-generic a week or two
ago, my T520 4940-49U won't boot. After 1-2 seconds, the screen goes
blank (dark - backlight off) and the laptop stops responding. Alt-F2,
etc does not cause any change. Alt-SysRq-B will reboot, but nothing
else has any effect. The hard disk light is not on/blinking.
Removing the "quiet splash $vt_handoff" options from the grub boot
options does NOT help; also adding "nofb" does NOT help; also adding
"init=/bin/bash" does NOT help.
Booting recovery mode for 3.5.0-27 DOES work. Booting 3.5.0-26 in
standard (non-recovery mode) DOES work.
I'm unable to capture any output from a failed boot, so not sure how
to troubleshoot further.
Attached data was captured while running 3.5.0-26 (NOT the problem
kernel).
