[Help] MPC8377 2.6.18 PCI-E doesn't work well

Hi All My board is MPC8377 with linux 2.6.18. When using the PCI-E device PCE9901, there is one serial can't work. The following is the message: /myapp # insmod 9900.ko 0001:02:00.0: ttyT0 at I/O 0x0 (irq = 22) is a starex-serial starex-serial: probe of 0001:02:00.1 failed with error -12

[PATCH 1/14] PM: Fix error code paths executed after failing syscore_suspend()

From: Rafael J. Wysocki r...@sisk.pl If syscore_suspend() fails in suspend_enter(), create_image() or resume_target_kernel(), it is necessary to call sysdev_resume(), because sysdev_suspend() has been called already and succeeded and we are going to abort the transition. Signed-off-by: Rafael J.
