I am using the "new" aic7xxx driver on a 2.4.4 IA64 kernel. I configured the kernel for DIG-compliant C0-stepping hardware. The kernel panic occurs in map_single (arch/ia64/lib/swiotlb.c:171). I have a 2-CPU Lion with C0-stepping CPUs. The requested IO TLB size is 8192 when the panic occurs. After the crash, I always have severe corruption on the filesystem that was being accessed during the crash. e2fsck reports ~10 illegal blocks in one inode, and many follow-up errors. The only TLB related boot message I see is kernel: Placing software IO TLB between 0xe000000000100000 - 0xe000000000300000 I am looking into this myself right now, but I would be grateful for hints where to start. Any help appreciated, Martin -- Martin Wilck FSC EP PS DS1, Paderborn Tel. +49 5251 8 15113
