Could I please see > dmesg with "i8042.debug log_buf_len=131072"? no custom keymaps . init=/bin/bash :d uhm, i don't get what you mean by this dmesg syntax :o i should probably attach serial conole and send you whole output, as now (as keyboard is unuseable) i can't scroll screen. btw. serio: i8042 KBD port at 0x60,0x64 irq 1 is found. also input: AT Raw Set 2 keyboard as /class/input/input1 is reported ah, i use gcc-4.1.1 to compile kernel . -------------------- stuff below might be result of my ignorance i just checked 2.2.27 kernel. it behaves quite identical to 2.4.33.3, just after 'freeing unused kernel memory' it touches disk , and just sits there. kepresses are echoed, and keyboard output is ok. i can reboot it by ctrl-alt-delete too . when i boot it with 'fosh' shell commandline appears, but trying to use any tool like bash, ls , etc results with signal 11. tools are statically compiled against glibc-2.4 (compiled for 486 cpu on gentoo) busybox works fine. on 2.4.33.3 kernel Xvesa (from kdrive package) complains 'set_thread_area failed when setting up thread-local storage' cardmgr works fine aswell...(though was linked against different glibc) i guess there is some problem with math emulation and glibc, as on 2.6.18 everything works just fine. i recall few years ago i tried to make 386SX work on 2.4.20 , and there were problems with math emulation (some apps worked, some not) - 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/
