Message-ID: <4F11503F.6000106@t-online.de> Date: Sat, 14 Jan 2012 10:51:59 +0100 From: Michael Mueller <malware@...nline.de> To: netdev@...r.kernel.org Subject: de4x5 (was Re: [PATCH] Making de2104x working with BNC connection on 21040 chipset) Hi Paul, I wrote [copy to you]: > The original de4x5 does not exist in 3.0. The comments at the top of My fault, it was not included into the compiled version of 3.1 for debian. > When trying the de4x5 using 2.6.32 - which is what I can boot into > without too much problems - it did lock the machine while starting the > interface (ifconfig up). Sorry, but I do not feel like digging into this > just now. I did try this with 3.1 now and it did lock up too but started printing out the cutting line of an oops. Replacing init by bash I got the remainder of a trace on the console. I could catch it on a serial console then: # insmod ./de4x5.ko [ 47.051976] de4x5 0000:02:04.0: PCI INT A -> Link[LNKB] -> GSI 11 (level, low) -> IRQ 11 [ 47.167825] 0000:02:04.0: DE434/5 at 0x9c00, h/w address 00:00:c0:e5:0c:c0 [ 47.250320] and requires IRQ11 (provided by PCI BIOS).
