The full transcript is attached. Thanks in advance. Could you try to reproduce this bug running onto a 2.4 host-skas kernel wit= h=20 the same guest kernel? Most people have no problem with the code; also, the= =20 host-skas patch for 2.6 that you used has more than one bug (somebody even = reported kernel Oopses with that applied). Also, I'd like more info on the = host configuration: glibc/gcc version and distro used. > NET: Registered protocol family 2 > > Breakpoint 1, schedule () at kernel/sched.c:1489 > 1489 if (likely(!(current->state & (TASK_DEAD | TASK_ZOMBIE)))) > { #0 schedule () at kernel/sched.c:1489 > #1 0xa002db4e in wait_for_completion (x=3D0xa1fefb64) at kernel/sched.c:= 1758 > #2 0xa0041104 in synchronize_kernel () at kernel/rcupdate.c:262 > #3 0xa000b5dc in inet_init () at net/ipv4/af_inet.c:1144 An old message, "[uml-devel] wait queues broken?" on 19 November 2003, spok= e=20 of something that could be related to this. Since everything is about=20 scheduling, this error message I got could be of interest: Kernel panic: Kernel mode fault at addr 0x1f, ip 0x400d1397 Kernel panic: kernel BUG at kernel/exit.c:793! The second message is of interest because the BUG line of interest reads as: schedule(); BUG(); and this is fairly interesting. To get this, I've run this command: while /bin/true ; do /bin/true ; done However, the kernel I was running went on after the "NET: Registered protoc= ol=20 family 2" message. --=20 Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 ------------------------------------------------------- SF.Net is sponsored by: Speed Start Your Linux Apps Now.
