Hi ,
Problem Description:
Firmware update using the update_flash -f<filename> results to soft lockup
BUG
FLASH: preparing saved firmware image for flash
FLASH: flash image is 50141296 bytes
FLASH: performing flash and reboot
FLASH: this will take several minutes. Do not power off!
BUG: soft lockup - CPU#1 stuck for 67s! [events/1:36]
Steps to reproduce:
1. Check the firmware information on the machine (using ASM or lsmcode)
2. Update the system firmware with the update_flash command
update_flash -f 01FL350_039_038.img
info: Temporary side will be updated with a newer or
identical image
Projected Flash Update Results:
Current T Image: FL350_039
Current P Image: FL350_039
New T Image: FL350_039
New P Image: FL350_039
Flash image ready...rebooting the system...
