Did apply it to my <br />2.6.15-rc5 and recompiled the whole kernel and all the drivers.<br /><br />Sadly this didn't affect the problem I have when starting X. The <br />Xorg.0.log looks still the same as before and I do have the '_' cursor<br />in the right left corner of the screen.<br />The only error in dmesg output is the following:<br /><br />kernel BUG at arch/sparc64/mm/generic.c:77!<br /> \|/ ____ \|/<br /> "&#64;'/ .. \`&#64;"<br /> /_| \__/ |_\<br /> \__U_/<br />X(6762): Kernel bad sw trap 5 [#1]<br />TSTATE: 0000000011009603 TPC: 0000000000434d60 TNPC: 0000000000434d64 Y: <br />00000000 Not tainted<br />TPC: &lt;io_remap_pfn_range+0x3c0/0x3e0&gt;<br />g0: fffff800007ee080 g1: 0000000000669400 g2: 0000000000000001 g3: <br />0000000000001df8<br />g4: fffff80001f30160 g5: 0000000000000010 g6: fffff80005c70000 g7: <br />0000000000000000<br />o0: 000000000000002f o1: 000000000061f118 o2: 000000000000004d o3: <br />0000000011812000<br />o4: 000001fc00610000 o5: fffff80001318c00 sp: fffff80005c7f271 ret_pc: <br />0000000000434d58<br />RPC: &lt;io_remap_pfn_range+0x3b8/0x3e0&gt;<br />l0: 0000000071804000 l1: 000001fb8edfe000 l2: 0000000071804000 l3: <br />000001fb8edfe000<br />l4: 000001fb8edfe000 l5: e000000000000f8a l6: a000000000000f8a l7: <br />c000000000000f8a<br />i0: 0000000071802000 i1: 0000000071802000 i2: fffff80000b90000 i3: <br />0000000071802000<br />i4: 80000000000006b0 i5: fffff80001db000c i6: fffff80005c7f361 i7: <br />000000000053b1e4<br />I7: &lt;sbusfb_mmap_helper+0x104/0x160&gt;<br />Caller[000000000053b1e4]: sbusfb_mmap_helper+0x104/0x160<br />Caller[0000000000533574]: fb_mmap+0x134/0x160<br />Caller[0000000000478708]: do_mmap_pgoff+0x368/0x720<br />Caller[00000000004161d8]: sys_mmap+0xf8/0x160<br />Caller[0000000000406c94]: linux_sparc_syscall32+0x34/0x40<br />Caller[0000000000286378]: 0x286378<br />Instruction DUMP: 9210204d 7fff6e12 90122118 &lt;91d02005&gt; 7ffff77f <br />b13e2000 81cfe008 01000000 30680003<br /><br /><br />I have to say I don't have much knowledge about the kernel code, but in <br />arch/sparc64/mm/generic.c it looks for me that no matter what if <br />io_remap_pte_range() is called it will result in a bug output, is this <br />supposed to happen?
