>From what I can tell, I think this patch ("printk: use the lockless
ringbuffer") breaks lx-dmesg in CONFIG_GDB_SCRIPTS.(gdb) lx-dmesg Python Exception <class 'gdb.error'> No symbol "log_first_idx" in specified context.: Error occurred in Python: No symbol "log_first_idx" in specified context. This command is used to dump the printk log buffer. It looks like the only places left in the kernel that reference are: - Documentation/admin-guide/kdump/gdbmacros.txt - Documentation/admin-guide/kdump/vmcoreinfo.rst - scripts/gdb/linux/dmesg.py I believe this commit removed log_first_idx, so all of the above probably need to be fixed up, too. ~ Nick
