Did apply it to my 2.6.15-rc5 and recompiled the whole kernel and all the drivers. Sadly this didn't affect the problem I have when starting X. The Xorg.0.log looks still the same as before and I do have the '_' cursor in the right left corner of the screen. The only error in dmesg output is the following: kernel BUG at arch/sparc64/mm/generic.c:77! \|/ ____ \|/ "@'/ .. \`@" /_| \__/ |_\ \__U_/ X(6762): Kernel bad sw trap 5 [#1] TSTATE: 0000000011009603 TPC: 0000000000434d60 TNPC: 0000000000434d64 Y: 00000000 Not tainted TPC: g0: fffff800007ee080 g1: 0000000000669400 g2: 0000000000000001 g3: 0000000000001df8 g4: fffff80001f30160 g5: 0000000000000010 g6: fffff80005c70000 g7: 0000000000000000 o0: 000000000000002f o1: 000000000061f118 o2: 000000000000004d o3: 0000000011812000 o4: 000001fc00610000 o5: fffff80001318c00 sp: fffff80005c7f271 ret_pc: 0000000000434d58 RPC: l0: 0000000071804000 l1: 000001fb8edfe000 l2: 0000000071804000 l3: 000001fb8edfe000 l4: 000001fb8edfe000 l5: e000000000000f8a l6: a000000000000f8a l7: c000000000000f8a i0: 0000000071802000 i1: 0000000071802000 i2: fffff80000b90000 i3: 0000000071802000 i4: 80000000000006b0 i5: fffff80001db000c i6: fffff80005c7f361 i7: 000000000053b1e4 I7: Caller[000000000053b1e4]: sbusfb_mmap_helper+0x104/0x160 Caller[0000000000533574]: fb_mmap+0x134/0x160 Caller[0000000000478708]: do_mmap_pgoff+0x368/0x720 Caller[00000000004161d8]: sys_mmap+0xf8/0x160 Caller[0000000000406c94]: linux_sparc_syscall32+0x34/0x40 Caller[0000000000286378]: 0x286378 Instruction DUMP: 9210204d 7fff6e12 90122118 <91d02005> 7ffff77f b13e2000 81cfe008 01000000 30680003 I have to say I don't have much knowledge about the kernel code, but in arch/sparc64/mm/generic.c it looks for me that no matter what if io_remap_pte_range() is called it will result in a bug output, is this supposed to happen? Looking at arch/sparc/mm/generic.c I can't find any similar functionality. -- //Aho ------------------------------------------------------------------------ E-Mail: trizt@iname.com URL: http://www.kotiaho.net/~trizt/ ICQ: 13696780 System: Linux System (PPC7447/1000 AMD K7A/2000) ------------------------------------------------------------------------ EU forbids you to send spam without my permission ------------------------------------------------------------------------ - 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/
