Comment in the diff says: /* IOMMU is always used to access "high mem" on those boxes * that can support enough mem that a PCI device couldn't * directly DMA to any physical addresses. * ISA DMA support will need to revisit this. */ > Please try a newer kernel, such as this one: > http://cvs.parisc-linux.org/download/linux-2.6/autobuild/712_defconfig/palinux-712-defconfig-2.6.15-pa4_0-2_all.deb Vincent, In case the newer kernel doesn't take care of it, can you manually copy down a few key lines of the panic: panic reason, IOAQ, top three lines of stack backtrace, gr24, gr25, gr26. thanks, grant _______________________________________________ parisc-linux mailing list parisc-linux@lists.parisc-linux.org http://lists.parisc-linux.org/mailman/listinfo/parisc-linux
