Fixed In Version: crash-4.1.2-4.el5_5.1
Doc Type: Bug Fix
Doc Text:
The "bt" subcommand of crash could not resolve the stack trace when an x86 NMI-interrupted task had just entered the kernel from user-space, but had not yet called the requested system call function. The same issue occurred when the resumption EIP address value of a newly forked x86 task was set to the "ret_from_fork" entry point by copy_thread(). This issue has been resolved in both cases.
