I have a dell 1535 laptop with the following wireless card: 0c:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01) it worked well until on day when I try either ndiswrapper and broacdom-sta on kernels >2.6.32 it crashes with similar dump, with lower kernel is just doesn't work. I have tried with windows xp, ubuntu 9.10, 10.04 and opensuse 11.3-Milestone7 in linux and ubuntu the card works without any problems and with opensuse it doesn't crash. what leads me to believe this might be a gentoo issue. I'm attaching my info. Reproducible: Always

Thank you for report. Could you tell us what drivers have you used in ubuntu? ndiswrapper?

Ok, then what version of broadcom-sta is there and what kernel ubuntu use?
(In reply to comment #6) > Ok, then what version of broadcom-sta is there and what kernel ubuntu use? > the driver version is 5.10.91 I think, kernel was 2.6.32 but when tried with opensuse at kernel 2.6.34 and latest broadcom driver, it didn't seg faulted when I've mod probed it, so did ndiswrapper
Ok, so basically we have two bugs here. For ndiswrapper could you to try 1.56 version. It's not in portage, so you'll have to bump it manually. Just `cp ndiswrapper-1.55-r1.ebuild ndiswrapper-1.56.ebuild`, then edit ebuild and drop epatch line and then run `repoman manifest`. For broadcom-sta. Following page suggests to use in-kernel drivers: http://en.opensuse.org/HCL/Network_Adapters_(Wireless)/Broadcom_BCM43xx site: "It is strongly recommended to use this driver rather than the Broadcom STA drivers which are reported to have stability and error-checking issues." Are you sure that you've used broadcom-sta drivers and not native in opensuse? If yes, could you check kernel version you've used? I doubt opensuse manages to provide 2.6.34 kernel since it was released on 16 May and following page suggests: http://en.opensuse.org/Package_List/11.2/KDE4-LiveCD-i686 that in most recent release they still use 2.6.31 kernel (and this means that yes, you have to use broadcom-sta driver since native support is not available for your chipset at that kenrel). So I suggest you to try broadcom-sta with most recent 2.6.32 kernel. Could you try suggested options here and report results, please?

no go with ndiswrapper-1.56, still crashes, will post trace later, I'm trying b34 now
ok, tried b43, after hard work, it seems to work. but still have problems to connect with the rc scripts, I need to run wpa_supplicant from cli, will try later t fix it and report.
it boots fine now, still what should I do with this bug?
Since broadcom-sta is known for being buggy and as I read this bug you haven't tried ndsiwapper in ubuntu/suse and thus it may crash there too, I guess there is nothing we can do at the moment. You could try to report ndiswrpapper issue upstream (and we'll borrow fixes with next release ;)) and broadcom-sta is also upstream issue. So resolving this bug as upstream. Still CC'ing developers just to check if interested.
