Hi, I'm trying to use the rtl8187 in the Fedora 8 kernel 2.6.23.14-107.fc8 on x86_64 and I'm having a number of problems with reliability. However, the most obvious problem is that the module cannot be removed. Attempting to rmmod the rtl8187 causes rmmod and ksoftirqd to go to 100% every time. The nvidia driver is loaded, but I can reproduce without it, and will do so and repost logs if necessary (easily). Also, I could switch to another kernel version (non-Fedora) if necessary (harder). The last message relevant to the removal in the log is: usbcore: deregistering interface driver rtl8187 I have a sysrq-Tasks dump also, and I'll try to paste the 'relevant' portions, but if you want something else, let me know: Jan 30 07:22:08 localhost kernel: rtl8187 S 0000000000000000 0 3080 2 Jan 30 07:22:08 localhost kernel: ffff8100582d3ee0 0000000000000046 0000000000000000 ffffffff8101bdf7 Jan 30 07:22:08 localhost kernel: ffff8100622f8820 ffffffff81370660 ffff8100622f8a98 ffffffff81370660 Jan 30 07:22:08 localhost kernel: ffffffffffffffff ffff81006add7000 0000000000000000 0000000000000000 Jan 30 07:22:08 localhost kernel: Call Trace: Jan 30 07:22:08 localhost kernel: [<ffffffff8101bdf7>] lapic_next_event+0x0/0xa Jan 30 07:22:08 localhost kernel: [<ffffffff810465f9>] worker_thread+0x0/0xe4 Jan 30 07:22:08 localhost kernel: [<ffffffff8104669a>] worker_thread+0xa1/0xe4 Jan 30 07:22:08 localhost kernel: [<ffffffff810493f5>] autoremove_wake_function+0x0/0x2e Jan 30 07:22:08 localhost kernel: [<ffffffff810492a0>] kthread+0x47/0x73 Jan 30 07:22:08 localhost kernel: [<ffffffff8100c9e8>] child_rip+0xa/0x12 Jan 30 07:22:08 localhost kernel: [<ffffffff810f26fa>] dummy_d_instantiate+0x0/0x1 Jan 30 07:22:08 localhost kernel: [<ffffffff81049259>] kthread+0x0/0x73 Jan 30 07:22:08 localhost kernel: [<ffffffff8100c9de>] child_rip+0x0/0x12 Jan 30 07:22:08 localhost kernel: rmmod R running task 0 5444 5331 (yes, there is NO call stack listed for rmmod...)
