Hi, today I got the following kernel bug while wpa_supplicant tried to connect to my AP. Kernel is a self-compiled 2.6.22 running under Ubuntu Feisty. The wireless device is a r8187 USB, the driver is patched for injection capability taken from www.aircrack-ng.org. Don't know if this bug is related to the driver or to the kernel, I'm no expert. Attached is the full dmesg and .config. Please CC to me, I'm not on the list. ------------[ cut here ]------------ kernel BUG at include/linux/timer.h:153! invalid opcode: 0000 [#1] PREEMPT Modules linked in: michael_mic ieee80211_crypt_tkip_rtl ieee80211_crypt_ccmp_rtl r8187 ieee80211_rtl ieee80211_crypt_rtl speedstep_ich speedstep_lib dm_crypt dm_mod fuse firewire_sbp2 ehci_hcd ohci_hcd pcmcia firmware_class usbhid firewire_ohci firewire_core nvidia(P) yenta_socket rsrc_nonstatic pcmcia_core crc_itu_t uhci_hcd floppy usbcore CPU: 0 EIP: 0060:[] Tainted: P VLI EFLAGS: 00010286 (2.6.22 #3) EIP is at ieee80211_associate_step1_rtl7+0x257/0x28d [ieee80211_rtl] eax: f2be5ae8 ebx: c045be90 ecx: f2be5cf8 edx: ffffffff esi: f2be53a0 edi: f741b380 ebp: 00000202 esp: f38a9f68 ds: 007b es: 007b fs: 0000 gs: 0000 ss: 0068 Process Ieee80211/0 (pid: 2635, ti=f38a8000 task=f38c8570 task.ti=f38a8000) Stack: ffffffff f2e9c210 f2be5b88 f2be53a0 f1bc11c0 f8f2600c f8f2606e f2be5b8c f2be5b88 c01276a6 001e8480 00000000 0000001d c0456198 f1bc11c8 f1bc11c0 c0127c55 00000000 c0127cf2 00000000 f38c8570 c012a784 f38a9fc0 f38a9fc0 Call Trace: [] ieee80211_associate_procedure_wq_rtl7+0x0/0x78 [ieee80211_rtl] [] ieee80211_associate_procedure_wq_rtl7+0x62/0x78 [ieee80211_rtl] [] run_workqueue+0x84/0x135 [] worker_thread+0x0/0xfb [] worker_thread+0x9d/0xfb [] autoremove_wake_function+0x0/0x37 [] worker_thread+0x0/0xfb [] kthread+0x33/0x54 [] kthread+0x0/0x54 [] kernel_thread_helper+0x7/0x18 ======================= Code: 43 c7 e9 5b ff ff ff 66 c7 86 c4 05 00 00 00 00 e9 2b ff ff ff 89 fa 89 f0 e8 b8 c3 ff ff eb c5 66 c7 86 c4 05 00 00 00 00 eb 9d <0f> 0b eb fe b9 fd 5c f2 f8 ba 1e 00 00 00 89 f8 e8 13 ca 3c c7 EIP: [] ieee80211_associate_step1_rtl7+0x257/0x28d [ieee80211_rtl] SS:ESP 0068:f38a9f68
