Keith:
I encountered an issue for ISR routine debug, the situation is:
1: When kdb is entered from keyboard, probably the IRQ
is enabled when it enter kdb(). Then if I set bp at do_IRQ and leave
kdb, the debug may be re-entered as soon as kdba_restoreint(..) is
completed in kdb(). That will cause kdb to be hanged because of LEAVING
flag not cleared correctly.
2: Even when kdb() is entered from former debug event,
if I set bp at do_IRQ and leave, the debug may be re-entered within
local_bh_enable() due to its IRQ enabled within this function, thus same
problem existed like above.
So what is your suggestion about this problem? If I don't make
mistake, probably we should move this 2 items to the end of function
kdb() and make a new release.
Eddie
