(version linux-2.4.18.tar.gz, kdb-v2.1-2.4.18-common-1 and kdb-v2.1-2.4.18-i386-1 No problem with that. I recompiled the kernel after enabling kdb in kernel hacking. I have installed the newly compiled kernel. My default run level was 5 (X windows). I had problem in bringing up X Windows. I changed the run level to 3. system cam up well. I could press 'pause' and enter into kdb. I could execute few commands. But as soon as I try to execute "go" command, system getting hanged. After that nothing works, keyboard getting locked. Also can we see the C Source in kdb? Have a nice time. Arun "Mihai RUSU" wrote: Hi I am using kdb 2.1 to hunt down a bug. This bug shows up after like 2 days of uptime. Problem is that also on this system I get a unkown reason NMI like: Uhhuh. NMI received for unknown reason 21. Dazed and confused, but trying to continue Do you have a strange power saving mode enabled? When it happens it enters kdb mode, thus the system "freezes". Because I cannot be there to issue a "go" everytime it happens (line 4 am :) ), it makes very hard to keep kdb enabled kernel running to wait for the hunted bug to happen. Is there a possibility to disable going to kdb mode when a "unkown reason" NMI is received ? I could not find any usefull info in the kdb docs. PS: this is the output from kdb on serial console when it receives the NMI: Entering kdb (current=0xcf142000, pid 31088) on processor 0 due to NonMaskable 3 eax = 0x00000051 ebx = 0x0804ebb0 ecx = 0x40017000 edx = 0x00000000 esi = 0x00000042 edi = 0x0804ebf8 esp = 0xbfffe094 eip = 0x08048fe3 ebp = 0xbfffe0ac xss = 0x0000002b xcs = 0x00000023 eflags = 0x00000202 xds = 0x0000002b xes = 0x0000002b origeax = 0x00000051 ?s = 0xcf143fc4 Thanks ---------------------------- Mihai RUSU - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ Get Your Private, Free E-mail from Indiatimes at http://email.indiatimes.com Buy Music, Video, CD-ROM, Audio-Books and Music Accessories from http://www.planetm.co.in - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
