Hi,
Here is a kernel oops using the latest fedora 12 kernel. Machine is a Intel(R) Xeon(R) CPU E5430 @ 2.66GHz, running in 32bit mode, normal SATA disks. Filesystem was created in fedora 10, and machine upgraded via yum to Fedora 12. Is reproducible using "stress-1.0.2" from http://weather.ou.edu/~apw/projects/stress/
Command line to reproduce was: ./stress --cpu 4 --io 1 --vm 1 --vm-bytes 128M --hdd 1
Please cc any reply to me, and all help is appreciated.
Cheers,
Rusty -- Rusty Conover rconover@infogears.com InfoGears Inc / GearBuyer.com / FootwearBuyer.com http://www.infogears.com http://www.gearbuyer.com http://www.footwearbuyer.com
