So I am not able to provide a backtrace. Well, there are at least some known bugs in -bb6 which are fixed in the new= =20 2.6 mainline patches. I fear that is not repeatable (but the 2.4 bug you=20 reported some time ago was repeatable, and I feel like this is a similar on= e,=20 so you could try). Note that to compile them you need to disable module support. Anyway, what = the=20 kernel has output actually *is* a backtrace. And why didn't you press Enter= =20 at the end, as it asks in the message? Anyway, it looks like something=20 known... it's not normal a so long backtrace. Again, try the later mainline= =20 patches. > Kernel panic: Kernel mode fault at addr 0x40007, ip 0x0 > In interrupt handler - not syncing > > EIP: 0000:[<00000000>] CPU: 0 Not tainted EFLAGS: 00000000 > Not tainted > EAX: 00000000 EBX: 00000000 ECX: 00000000 EDX: 00000000 > ESI: 00000000 EDI: 00000000 EBP: 00000000 DS: 0000 ES: 0000 > Call Trace: [] notifier_call_chain+0x2d/0x50 > [] panic+0xab/0x130 > [] arch_fixup+0x11/0x30 > [] segv+0x201/0x230 > [] sig_handler_common_skas+0x81/0xa0 > > [] sig_handler+0x18/0x20 > [] change_signals+0x73/0xa0 > [] segv_handler+0xd7/0xe0 > [] unblock_signals+0x12/0x20 > [] sig_handler_common_skas+0x81/0xa0 > [] sig_handler+0x18/0x20 > > [] free_block+0x31/0xd0 > [] handle_IRQ_event+0x4e/0x70 > [] do_IRQ+0x94/0xd0 > [] sigio_handler+0x3d/0x130 > [] sig_handler_common_skas+0x81/0xa0 > [] sig_handler+0x18/0x20 > > [] set_signals+0xfc/0x1c0 > [] set_signals+0xfc/0x1c0 > [] get_signals+0x84/0xb0 > [] set_signals+0xfc/0x1c0 > [] set_signals+0xfc/0x1c0 > [] change_signals+0x73/0xa0 > > [] get_signals+0x84/0xb0 > [] change_signals+0x73/0xa0 > [] __virt_to_page+0x11/0x30 > [] drain_array+0x67/0xa0 > [] reap_timer_fnc+0x67/0x1c0 > [] reap_timer_fnc+0x0/0x1c0 > > [] run_timer_softirq+0xc4/0x190 > [] __do_softirq+0xa5/0xb0 > [] do_softirq+0x45/0x50 > [] do_IRQ+0xcb/0xd0 > [] timer_irq+0x150/0x190 > [] timer_handler+0x2b/0x30 > > [] sig_handler_common_skas+0x81/0xa0 > [] start_kernel_proc+0x0/0x30 > [] new_thread_handler+0x0/0x100 > [] alarm_handler+0x29/0x60 > [] sig_handler+0x18/0x20 > [] new_thread_handler+0x0/0x100 > > [] start_kernel_proc+0x0/0x30 > [] default_idle+0x45/0x70 > [] set_signals+0xfc/0x1c0 > [] set_signals+0xfc/0x1c0 > [] set_signals+0xfc/0x1c0 > [] switch_threads+0x5f/0x60 > > [] get_signals+0x84/0xb0 > [] change_signals+0x73/0xa0 > [] unblock_signals+0x12/0x20 > [] finish_task_switch+0x27/0x70 > [] schedule+0x28f/0x400 > [] new_thread_handler+0x0/0x100 > > [] idle_sleep+0x24/0x30 > [] default_idle+0x5d/0x70 > [] new_thread_handler+0x0/0x100 > [] rest_init+0x21/0x30 > [] init+0x0/0x100 > [] init_idle_skas+0x25/0x30 > > [] start_kernel+0x149/0x170 > [] unknown_bootoption+0x0/0x120 > [] block_signals+0x12/0x20 > [] start_kernel_proc+0x29/0x30 > [] start_kernel_proc+0x0/0x30 > [] run_kernel_thread+0x49/0x50 > > [] start_kernel_proc+0x0/0x30 > [] new_thread_handler+0x0/0x100 > [] run_kernel_thread+0x2e/0x50 > [] start_kernel_proc+0x0/0x30 > [] new_thread_handler+0x0/0x100 > [] new_thread_handler+0xae/0x100 > > [] start_kernel_proc+0x0/0x30 > [] new_thread_handler+0x0/0x100 > [] new_thread_proc+0x1d/0x30 > > ---Type to continue, or q to quit---Detaching after > fork from child process 1937. > > > Program exited with code 01. > (gdb) > > > > ------------------------------------------------------- > SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media > 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 > Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. > http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 > _______________________________________________ > User-mode-linux-devel mailing list > User-mode-linux-devel@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/user-mode-linux-devel --=20 Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
