However, when i came back from work today i found the following message from kernel after doing 'dmesg': Debug: sleeping function called from invalid context at include/asm/uaccess.h:473 Call Trace: [] __might_sleep+0x5d/0x70 [] save_v86_state+0x6a/0x200 [] do_IRQ+0xd5/0x110 [] work_notifysig_v86+0x6/0x14 [] syscall_call+0x7/0xb The system has not crashed or anything, everything is fine, but i just wanted to point this out in case it may be of interest for kernel developers. Unfortunately this msg seems to have been emitted while i was away, so i can't give more detailed info about the conditions in which happened. All i can say is the box was basically idle, just running X with a couple of terminals and the screensaver. Sorry in advance if this message is just a piece of useless rubbish, i know basically nothing about kernel internals. PS: I am not subscribed to the list, please CC me when answering. Thanks, -- axel c
