Incidentaly kdb acts a little strange elsewhere with the swapper process. If it's an active process it'll list it in ps and begin with it selected, but if it's not you won't see it in ps and can't select it (with the pid command) because for_each_task() doesn't enumerate it.

I >guess it's something worth debugging, so this should be fixed? kdb v4.4 adds a new process state, 'I' for idle. The swapper[*] task will have this state if it is truly idle, i.e. it is not servicing an interrupt. Both ps and btc will not show tasks in state 'I' by default, these tasks contain no useful data and they fill up the output on large machines. Instead kdb v4.4 will print a line like this idle cpus, use ps I to see them: 0, 2-4, 7-21, 22-255 SGI have machines with large cpu counts. [*] I assume you know that the swapper task does not really swap. The name is a hangover from 2.0 kernels where it handled swapping directly. Now the idle task just spins and may service interrupts.

You have a misapplied patch to arch/i386/kernel/traps.c. It is calling lkcd before kdb. die() in arch/i386/kernel/traps.c should look like this. void die(const char * str, struct pt_regs * regs, long err) { console_verbose(); spin_lock_irq(&die_lock); bust_spinlocks(1); handle_BUG(regs); printk("%s: %04lx\n", str, err & 0xffff); show_registers(regs); bust_spinlocks(0); spin_unlock_irq(&die_lock); #ifdef CONFIG_KDB kdb_diemsg = str; kdb(KDB_REASON_OOPS, err, regs); #endif /* CONFIG_KDB */ dump((char *)str, regs); do_exit(SIGSEGV); } Note that dump() is called after kdb.

Some kernels can be configured to interpret an RS-232 break condition as a sysrq key. I don't remember the name of the pertinent configuration variable. Then all you have to do is figure out how to make your terminal emulation program generate a break and you can generate sysrq-c thru a serial port.

[snip example] Yup, that was it, patch went in crooked. I tried applying the kdb and lkcd patches in different orders, and there's no one order that works cleanly. Seems like there ought to be a combined lkcd/kdb patch since these two entities work so closely together, especially in light of the fact that the kdb readme contains an additional patch for lkcd. Although, that's just one more thing to test that no-one ever has time for. Thanks for your help. -Bruce Use http://oss.sgi.com/ecartis to modify your settings or to unsubscribe.

I added a bunch of printk's to figure out where it was hanging, and it just ends up spinning in kiobuf_wait_for_io() (fs/iobuf.c). The kiobuf->io-count never decrements. It doesn't do this if I set a breakpoint at dump_execute_memdump(). The dump completes successfully when I type "go" after it hits the breakpoint. Is this a case of kdb stopping all but one CPU, thereby not letting the thread handling the disc writes run? Or, is some interrupt mask being set by kdb that the breakpoint re-enables?

I have the current RedHat 9.0 source tree, which is linux 2.4.20-8

I downloaded and applied the patches for kdb v4.3  but they failed to patch properly:

        kdb-v4.3-2.20-common-1.bz2
        kdb-v4.3-2.20-i386-1.bz2

Should I be using a different patch?
