Description of problem: Getting the following trace on the console of a freshly installed Fedora Core 2 box. Badness in interruptible_sleep_on_timeout at kernel/sched.c:2533 [<02281cc0>] interruptible_sleep_on_timeout+0x5d/0xb1 [<02115e4e>] default_wake_function+0x0/0xc [<02239cd5>] netdev_run_todo+0x22/0x1ac [<06881d8f>] rtl8139_thread+0x38/0x134 [8139too] [<06881d57>] rtl8139_thread+0x0/0x134 [8139too] [<021041d9>] kernel_thread_helper+0x5/0xb I already upgraded from the stock kernel from the CD distribution. Version-Release number of selected component (if applicable): kernel-utils-2.4-9.1.131 kernel-2.6.6-1.435 How reproducible: Every minute. Every time I boot. I have googled/searched bugzilla and found a couple of similar issues but these were for a different module and different versions and I did not think they were appropriate. These were for #116864 and #125482. Do I need to upgrade the kernel further. If so where would I find such a kernel? Thanks Nick
Updates for kernel available from up2date or try 'yum update' Don't know if this will solve it, but if all is running Ok it may not be a serious problem. Jerry
This still is happening in the 2.6.8-1.521 kernel. This is the latest kernel from updates.

One bug suggested that this was an NFSd locking issue (#134006 IIRC)
No lockd_down just performs a completely invalid and unsafe sleep that the new debugging code catches. Its a fairly obvious "duh" bug that needs switching to use the unrolled wait_for_event functionality.

Created attachment 105198 [details] my proposed patch to fix this problem Its my understanding that this is caused by a non-upstream patch that was added to RHEL4 which removed the holding of the BLK lock. When I send the upstream version my patch that removed these warnings, it was strongly advised (in which I have to agree) not to remove the holding BLK lock. So I would suggest we remove the "removing of the BLK lock" patch.
Looks sane to me

Still seeing this problem on 2.6.9-1.681_FC3.
I continue to get the following with FC2 2.6.9-1.6 when trying to load a second lirc module. First module works OK. ledxmit_dev: IR Remote Control driver registered, at major 72 Badness in sleep_on_timeout at kernel/sched.c:3022 [<02308ff6>] sleep_on_timeout+0x5d/0x23a [<0211bba1>] default_wake_function+0x0/0xc [<02125ae4>] __request_region+0x56/0x79 [<42c968c8>] init_port+0x1cb/0x22f [ledxmit_serial] [<42c972e3>] init_module+0x33/0x89 [ledxmit_serial] [<0213c2af>] sys_init_module+0x207/0x2ef ledxmit_serial: auto-detected active high receiver ledxmit_dev: ledxmit_register_plugin:sample_rate: 0
That lirc module appears buggy. The kernel is trapping this because we ship the FC kernels with some of the low overhead debugging functionality enabled. Alan
