After applying the hotfixes from Andrew's repository and the patches from the mailing lists listed below, I'm booting 23-rc1-mm1 with a zx1 specific config [on an sx1000]. Gotta run for a meeting, but I'll try generic kernel this pm. Then back to testing memoryless node patches, ... Other "hot fixes": 2 of Mel Gorman's patches to fix ia64 mmap corruption [mm list] Yasuaki Ishimatsu's assign irq vector fix [ia64 list] Kenji Kaneshige's "wrong access to vector" patch [ia64 list] Kame-san's sparsemem-vmemmap fix [lkml] Lee - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
