I just looked at my logs and realised I add a similar oops in my log. It happened a few days ago on 2.6.0-test10 (I failed to notice because everything seems to work fine).
Here is what I have :
Badness in local_bh_enable at kernel/softirq.c:121 Call Trace: [<c01251d3>] local_bh_enable+0x93/0xa0 [<f997dced>] ppp_async_push+0xbd/0x1b0 [ppp_async] [<f997d58e>] ppp_asynctty_wakeup+0x2e/0x70 [ppp_async] [<c01cc619>] pty_unthrottle+0x59/0x60 [<c01c8c1b>] check_unthrottle+0x3b/0x40 [<c01c8cd3>] n_tty_flush_buffer+0x13/0x60 [<c01cca2d>] pty_flush_buffer+0x6d/0x70 [<c01cc9c0>] pty_flush_buffer+0x0/0x70 [<c01c4ee3>] do_tty_hangup+0x4e3/0x580 [<c01c6752>] release_dev+0x742/0x780 [<c013f82c>] __pagevec_free+0x1c/0x30 [<c014487e>] release_pages+0x7e/0x1a0 [<c0171bb1>] dput+0x31/0x270 [<c01c6b7b>] tty_release+0x3b/0x90 [<c015a3db>] __fput+0x10b/0x120 [<c01588e9>] filp_close+0x59/0x90 [<c0122634>] put_files_struct+0x64/0xd0 [<c01233cf>] do_exit+0x19f/0x4c0 [<c01237c2>] do_group_exit+0x42/0xe0 [<c0109539>] sysenter_past_esp+0x52/0x71
The previous line in my logs was from my TI acx100 wifi card. It runs with the experimental driver from http://acx100.sf.net. So if this oops can be caused by bad driver behaviour, please ignore.
I am using ppp with pppoe on a ne2k-pci network board.
I have smp (dual-p3) and preemption enabled. The kernel is compiled with gcc 3.3.1-2 from debian sid.
