Hi, I'm experiencing Kernel oopses when I utilize capi using c2faxsend to send a fax. I can reproduce this on every fax which I try to send. The ISDN Card installed in the Server is a AVM B1 4.0 PCI I have not yet tried 2.6.12.4 as I have not found anything related to this in the Changelog .config File is attached. Regards Carsten Here is the stack trace: kcapi: appl 3 ncci 0x10101 forced down kcapi: appl 3 ncci 0x10101 down Unable to handle kernel paging request at virtual address 00100104 printing eip: e09b4e12 *pde = 00000000 Oops: 0002 [#1] PREEMPT SMP Modules linked in: ipv6 b1pci b1dma b1 n_hdlc tun capi capifs kernelcapi evdev pcspkr parport_pc parport psmouse genrtc e1000 ide_cd cdrom ide_disk ide_generic pdc202xx_new aec62xx alim15x3 amd74xx atiixp cmd64x cs5520 cs5530 cy82c693 generic hpt34x ns87415 opti621 pdc202xx_old rz1000 sc1200 serverworks siimage sis5513 slc90e66 triflex trm290 via82cxxx floppy usb_storage piix ide_core fbcon font bitblit vga16fb usbhid usbkbd ehci_hcd uhci_hcd thermal processor fan unix CPU: 1 EIP: 0060:[] Not tainted VLI EFLAGS: 00010292 (2.6.12.3) EIP is at capilib_release_appl+0x52/0x70 [kernelcapi] eax: 00100100 ebx: d914c080 ecx: c03c5a94 edx: 00200200 esi: dec8ee4c edi: dec8ee4c ebp: 00000003 esp: d4ddbdb4 ds: 007b es: 007b ss: 0068 Process c2faxsend (pid: 5499, threadinfo=d4dda000 task=d4871a60) Stack: e09b7960 00000003 00010101 dec8ecc8 00000003 decc6000 de8f2968 e0c6bb29 dec8ee4c 00000003 000000e2 dec8ecc8 d6c03288 dff85300 e09b20ba dec8ecc8 00000003 00000000 e09b2d00 dec8ecc8 00000003 d6c03280 00000000 e0949653 Call Trace: [] b1dma_release_appl+0x29/0xe0 [b1dma] [] release_appl+0x1a/0x70 [kernelcapi] [] capi20_release+0xc0/0xd0 [kernelcapi] [] capidev_free+0x93/0xa0 [capi] [] capi_release+0x19/0x30 [capi] [] __fput+0x12a/0x140 [] filp_close+0x59/0x90 [] put_files_struct+0x64/0xd0 [] do_exit+0xee/0x380 [] do_group_exit+0x40/0xb0 [] get_signal_to_deliver+0x233/0x340 [] do_signal+0x9b/0x130 [] wake_up_state+0x18/0x20 [] signal_wake_up+0x2e/0x50 [] force_sig_info+0x71/0xb0 [] force_sig+0x20/0x30 [] do_general_protection+0x90/0x1c0 [] copy_to_user+0x42/0x60 [] sys_gettimeofday+0x3c/0x90 [] do_general_protection+0x0/0x1c0 [] do_notify_resume+0x37/0x3c [] work_notifysig+0x13/0x15 Code: f3 39 fb 8b 36 75 f2 83 c4 0c 5b 5e 5f 5d c3 8b 43 0c 89 6c 24 04 c7 04 24 60 79 9b e0 89 44 24 08 e8 63 95 76 df 8b 53 04 8b 03 <89> 50 04 89 02 c7 43 04 00 02 20 00 c7 03 00 01 10 00 89 1c 24 -- "There are two major products that came out of Berkeley: LSD and UNIX.
