BTW, I forgot to mention it is 2.4.31 kernel and LKCD 4.1.1. The comment in driver/dump/dump_base.c mentioned about problem in dumping within interrupt handler. Can someone give me an example? In general, I heard about no sleeping in interrupt context. Is that still true in 2.6 with preemptable kernel? Thanks. -----Original Message----- From: kernelnewbies-bounce@xxxxxxxxxxxx [mailto:kernelnewbies-bounce@xxxxxxxxxxxx] On Behalf Of Tony Chung Sent: Monday, December 25, 2006 9:52 AM To: kernelnewbies Subject: hardware watchdog reset during LKCD Hi All, I try LKCD and it was working fine but when hardware watchdog is enabled, it reset the system in the middle of crash dump. This hardware watchdog only allow a maximum of 60 seconds otherwise I will increase the timeout. I could modify the LKCD to stop the hardware watchdog but that may not a good solution since there are so many types of hardware or even software watchdog. Is there a way to notify a user daemon process to stop the hardware watchdog? I noticed the panic.c called notifier_call_chain(). How does it work? Any hints or pointers? Or is there a simple way to handle the watchdog reset problem? Thanks. - Tony -- Kernelnewbies: Help each other learn about the Linux kernel.
