> Attached the boot log and config file. Kamelesh,
I don't see anything obvious in the boot_log. I used your "dotconfig" file to build a 2.6.23-rc3-mm1 kernel and booted it on my test system ... it worked just fine (except that for some reason the network did not come up :-( ) I tried to compare my boot log with yours ... you have some different devices (E.g. your ethernet links are Tigon3 while mine are e1000) ... so the memory leak in a driver theory is a possibility. Try adding a dump_stack() call to lib/swiotlb.c where the "DMA: Out of SW-IOMMU space ..." message is printed. That would tell us who is making the call that fails (they might be an innocent bystander after someone else has used all the space ... but this is unlikely). -Ton - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
