My Kernel is not a standard kernel (I have had to tweek it to get the SBUS GC3 and the 82077 floppy to work on my OPUS Sparc 1 clone). Can you advise me on any known issues in the NFS Client code that might enter NULL pointers into the 'slot->slots[i]' in __lookup_tag. If there are none that you are aware of, are there any specific areas that I should investigate with printk statements. The Kernel is cross compiled on an Athlon 64 3400+ (32bit linux at the moment) using GCC-4.0.2 and Binutils-2.16.1. Compilation takes about 10 minutes so there is no real issue in making changes to the kernel to find the source of the problem. A compiler/binutils bug should not be ruled out. I might try gcc-3.4.3/binutils-2.15. Please let me know if you would like further information. Regards Mark Fortescue. -------------------------------------------------------------------------- kernel BUG at /L64/src/linux-2.6/linux-2.6.13.4-p01/lib/radix-tree.c:575! \|/ ____ \|/ "@'/ ,. \`@" /_| \__/ |_\ \__U_/ ld(45): Kernel bad trap [#1] PSR: 004000c4 PC: f00e0ff4 NPC: f00e0ff8 Y: 00000000 Not tainted PC: %G: 00000001 f022ec00 f022eccc 00400fe2 f002fd18 f022ec00 ff020000 00000000 %O: 0000004d f01fbd78 0000023f 00000000 00000001 00000000 ff021a48 f00e0fec RPC: %L: 00000001 ff021b14 0000003f 00000001 00000002 00000000 ff020000 e0162000 %I: 00000000 ff021b14 00000000 00000001 00000008 ff021b10 ff021ab0 f00b10d4 Caller[f00b10d4]: nfs_wait_on_requests+0x98/0xb8 Caller[f00b2a70]: nfs_sync_inode+0x20/0x74 Caller[f00b063c]: nfs_readpage+0x44/0x44c Caller[f004fc8c]: do_generic_mapping_read+0x290/0x564 Caller[f005084c]: __generic_file_aio_read+0x168/0x1cc Caller[f0050a2c]: generic_file_aio_read+0x44/0x54 Caller[f006e298]: do_sync_read+0x94/0xc8 Caller[f006e62c]: vfs_read+0xa0/0x15c Caller[f006f200]: sys_read+0x30/0x64 Caller[f001144c]: syscall_is_too_hard+0x34/0x40 Caller[e0096e58]: 0xe0096e58 Instruction DUMP: 90122178 7ffcc514 01000000 <91d02005> 9402a001 80a28010 0280000f c4244001 8600e001 -------------------------------------------------------------------------- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
