Ok, I have another box which has had the same failure (rocketport serial ports stoped working after 248 days and 16 hours). I have about 2 more hours before I need to reboot the box and get it back into production. I have both a working and non-working example, where I have re-compiled and re-loaded the rocketport module with the debugging info turned on. On my working example: # when I load the module the init function gets called int rp_init(void) # when I cat from the tty device the open function gets called static int rp_open(struct tty_struct *tty, struct file * filp) # # then somehow automagically the rp_handle_port() gets called by # rp_do_poll()... and data gets read void rp_handle_port(struct r_port *info) static void rp_do_poll(void) On my non-working example: # the init and the open seem to hapen fine, however the rp_do_poll() never # gets called?! I see that in rp_init(), rp_do_poll() gets saved to a "structure" called "timer_table[COMTROL_TIMER].fn = rp_do_poll;", however I have yet to find what that is. Where else could I look to find the problem? I am working with kernel 2.2.14 (/usr/src/linux/drivers/char/rocket.c), which except for two lines is the same in 2.2.17. I am not yet subscribed to the kernel list, so please cc responses to me.
