Hi Laurent, On the beagleboard list, we found a hack/workaround for the smsc95xx kevent spam in dmesg, that seems to lock up the ethernet interface: Add to /etc/sysctl.conf: vm.min_free_kbytes = 8192 So far, after 13 hours, my panda hasn't had a single kevent while building gcc and running the gcc testsuite, with a setting of -j 3..

Robert and Laurent, How about your U-Boot, does it recognize the whole 1G memory or just 512M memory. Without any mem= option in kernel cmdline, kernel will get such memory information from U-Boot, IMHO. My U-Boot recognize the whole 1G memory, then even without mem=1G, Kernel will get the whole 1G physical memory on board.

[Bug 690370] Re: Strange out of memory on pandaboard
I first did a simple test: leave the pandaboard idle, after 5 days no crash. Robert, I followed your instructions but after reboot I have only the serial console and no network. It seems because my boot.script has smsc95xx.macaddr=32:57:F8:93:E1:CD and it looks like it blocks loading of the module with the newer kernel: [ 474.915527] smsc95xx: Unknown parameter `macaddr' I've found no way to tell modprobe to not pass macaddr. After I edit /boot/boot.script to remove this option when I run flash-kernel I get Unsupported platform. So I looked at flash-kernel code and ran manually the line to update boot.scr and managed to reboot with network this time (but another MAC address ...) Then it looks like I lost some memory (I removed the line mem= and Mem:489252k total,88104k used, 401148k free, 5700k buffers Here is my /proc/cmdline: # cat /proc/cmdline text ro root=UUID=b5d2dfb1-270c-4966-abe6-dfe7a2a17efd console=ttyO2,115200n8 I removed elevator=noop vram=32M mem=768M since you made no mention of those.
