Hi,
I just left my 2.5.44 box unattended for hour and half, and when
I came back, I saw very strange things on screen:Machine did it again yesterday 7:55 morning, after having ~10 hours uptime. All three dumps are same, with minor difference in last one:
*pde is024c4067, and Process line is 'cat (pid: 11497, threadinfo=c3960000, task=d1c3a780)'... All other values are same.
I'm getting really nervous :-( Is kdb able to track who caused unbalanced in_atomic() incrementation?
After more than week of stable system I run simple
"arp vanicka.vc.cvut.cz" few minutes ago, and after arp output I got sleeping function called from illegal context, quickly followed by two scheduling while atomic, and finally it died because of userspace faults when in_atomic() is != 0 are treated as kernel ones...
As I saw nobody else reporting this or simillar problem, I'll start looking at e100 driver I use. Maybe it did not occured because of I was running -acX kernels since 25th Oct until yesterday. Anybody knows?
Thanks,
