NMI Watchdog detected LOCKUP on CPU1, eip c02f2750, registers: eax: d64ca000 ebx: c24d5400 ecx: c24bb000 edx: 00000000 ds: 0018 es: 0018 ss: 0018 How do I make some sence of it? I've had a look in /proc/ksyms but c02f2750 isn't listed. Is there some other list I should be asking on? A URL I should be looking at? I'm very new to kernel debugging/troubleshooting and I'm a bit lost..... though not quite as lost as I was yesterday ;) Thanks.... Nick -- [EMAIL PROTECTED] mailing list
