Hi, I'm using kernel 2.6.26.8-rt13 with CONFIG_DYNAMIC_FTRACE=y set. When loading a kernel object the following message appear: BUG: sleeping function called from invalid context insmod(1370) at include/asm/uaccess_32.h:560 in_atomic():0 [00000000], irqs_disabled():1 Pid: 1370, comm: insmod Not tainted 2.6.26.8-rt13-heros5 #8 [<c011e13e>] __might_sleep+0xe5/0xea [<c011439a>] ftrace_modify_code+0x22/0xa6 [<c0114364>] ? ftrace_test_p6nop+0x0/0xa [<c0162fb4>] __ftrace_update_code+0xed/0x2cf [<c0114364>] ? ftrace_test_p6nop+0x0/0xa [<c0163730>] ftrace_convert_nops+0x57/0x73 [<c0163761>] ftrace_init_module+0x15/0x17 [<c01491da>] sys_init_module+0x14c9/0x1a7d [<c016d89d>] ? generic_file_aio_read+0x49a/0x4d6 [<c0311ef9>] ? sub_preempt_count+0xa2/0xb0 [<c02180c4>] ? strpbrk+0x0/0x2b [<c019b7b9>] ? dput+0x34/0xe4 [<c0104b31>] sysenter_past_esp+0x6a/0x99 ======================= Is it not possible to use rt-patches and dynamic tracepoints? -Andreas
