(2.6.11-rc4-pa1) Could run spew+"make -j4" over xfs without crashing the box (panic). Then I rebooted with a freshly built kernel (and "noudev") and right away when I start spew on the XFS file system I get: Kernel Fault: Code=26 regs=00000000fd0b0de0 (Addr=00000000000000c8) ... IAOQ[0]: xfs_btree_init_cursor+0x70/0x1b8 [xfs] IAOQ[1]: xfs_btree_init_cursor+0x8c/0x1b8 [xfs] RP(r2): xfs_btree_init_cursor+0x58/0x1b8 [xfs] The system panics with and without the xfs patches Joel pointed me at. The only difference in the .config was sym2 driver IOMAPPED. I had it enabled (using IO Port space) and now disable it since I really want MMIO space. I'm very skeptical this is related to the problem. > If your compile time options include devfs, try turning it > off also. Use the command line option: 'nodevfs' I don't use devfs.

Is there a difference in the how the devices are used? ie. serialized vs. multiple IOs in flight at the same time? I didn't start hitting problems until I lauched a second job on the same file system. thanks, grant _______________________________________________ parisc-linux mailing list parisc-linux@lists.parisc-linux.org http://lists.parisc-linux.org/mailman/listinfo/parisc-linux
