Hi everybody, unfortunately Andrew's path can be proven to be wrong: There is no bug in the ACPI area at all. I reverted the following modules in 2.6.22-rc2-mm1: --- linux-2.6.22-rc2/drivers/net/b44.c 2007-05-19 02:24:07.000000000 -0700 +++ devel/drivers/net/b44.c 2007-05-22 21:55:36.000000000 -0700 AND: --- linux-2.6.22-rc2/drivers/net/b44.h 2007-04-25 23:42:17.000000000 -0700 +++ devel/drivers/net/b44.h 2007-05-22 21:55:36.000000000 -0700 AND: --- linux-2.6.22-rc2/drivers/usb/host/ohci-hcd.c 2007-05-19 02:24:07.000000000 -0700 +++ devel/drivers/usb/host/ohci-hcd.c 2007-05-22 21:55:36.000000000 -0700 AND: --- /dev/null 2007-05-07 19:14:32.301975000 -0700 +++ devel/drivers/usb/host/ohci-ssb.c 2007-05-22 21:55:36.000000000 -0700 RESULT: Broadcom 4401 is working purrfectly! YUP! Apart from that the kernel configuration menu of 2.6.22-rc2-mm1 is highly confusing: Kernel Config differences: In kernel 2.6.21.2 you are bound to go: EISA, VLB, PCI and onboard controllers Y Broadcom 4400 ethernet support m Whereas in Kernel 2.6.22-rc2-mm1 is completely confusing: 1. There is a menu called Sonics Silicon Backplane, which does not exist in 2.6.21.2. 2. In Section Network device support Y Ethernet (10 or 100Mbit) Y you got 2 confusing choices: Option A: EISA, VLB, PCI and onboard controllers Y Broadcom 4400 ethernet support m Broadcom 4400 PCI device support y This enables "Sonic Silicon Backplane support m" OR, and this is in fact confusing: Option B: Leave OUT (!!!) EISA, VLB, PCI and onboard controllers Y Simply: Broadcom 4400 ethernet support m This enables "Sonic Silicon Backplane support m" Option B is proved to be working with the patch against the b44.c module reverted in 2.6.22-rc2-mm1. If it is NOT reverted, Option B fails, but the confusion stays: You do not get the idea whether "Support for SSB on PCI bus host m" is necessary or not! And above that, THIS ONE: "Broadcom 4400 ethernet support m" should never appear when THIS one: "EISA, VLB, PCI and onboard controllers Y" is DESELECTED, should it?? And that's it exactly what I meant when I mentioned that the ATTACHMENT of ssb to b44 is highly buggy! I hope, Michael, that you believe that now. If you need lspci -v or / and dmesg to prove that I am right and you are wrong: Pleasure for me, just ask please! Cheers Uwe P. S.: In clear words: I higly suspect that simply the kernel config bindings are highly buggy and chaotic. - To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
