When I try to connect my laptop to the interenet while running dhcp either ifconfig/dhcpcd crashes with page allocation failure. order:8 mode:0x21 This is the stack trace from kernel logs Jan 31 00:36:58 [kernel] ifconfig: page allocation failure. order:8, mode:0x21 Jan 31 00:36:58 [kernel] dhcpcd: page allocation failure. order:8, mode:0x21 Jan 31 00:36:58 [kernel] [<c0136193>] __alloc_pages+0x223/0x360 Jan 31 00:36:58 [kernel] [<c01362e8>] __get_free_pages+0x18/0x40 Jan 31 00:36:58 [kernel] [<c0108a44>] dma_alloc_coherent+0xc4/0x100 Jan 31 00:36:58 [kernel] [<e1334c58>] b44_alloc_consistent+0x98/0x150 [b44] Jan 31 00:36:58 [kernel] [<e1335151>] b44_open+0x21/0xe0 [b44] Jan 31 00:36:58 [kernel] [<c026129d>] dev_open+0x7d/0x90 Jan 31 00:36:58 [kernel] [<c026271f>] dev_change_flags+0x5f/0x150 Jan 31 00:36:58 [kernel] [<c029d83b>] devinet_ioctl+0x54b/0x600 Jan 31 00:36:58 [kernel] [<c029f9ba>] inet_ioctl+0xca/0xe0 Jan 31 00:36:58 [kernel] [<c025868d>] sock_ioctl+0x19d/0x250 If I reboot into my 2.6.9-r9 kernel I dont have that problem. I need to reboot an whole bunch of time before it can pick up the ip through dhcp. If I reboot after that then I have the same problem again and again. Reproducible: Always Steps to Reproduce: 1. modprobe b44 2. bring up interface using dhcp 3.

Could you please test development-sources-2.6.11_rc2?
I emerged development-sources-2.6.11_rc2 and it worked perfectly, no problem at all.
Can't see which patch between 2.6.10 and 2.6.11 solves this. Leaving open for now, incase someone else can contribute info.
I think I have seen this or a similar issue in the past with various random kenels but I was able to resolve it by compileing dhcpcd again. What the real issue is I don't know, it's never happened to me when I had time to debug it.
I tried recompiling not just dhcpd but also my kernel. I have compiled it 3-4 times but I still keep getting this crash. I am sticking to my wireless connection for now. It seems to be real pain not to be able to use your wired connection if there is no wireless access point. I currently reboot to the 2.6.11-rc3 kernel whenever I need to use the wired connection it hasnt given me any problem at all.
gentoo-dev-sources-2.6.11 is now in portage
