Hi, guys
To get wireless to operate successfully in my laptop (broadcom 802.11b/g), i had to install NDISWRAPPER and use a windows driver.
Unfortunatelly, fedora kernel uses a 4 k stack size, and windows driver demands of 8 or 16 k (i don't know exactly which size) stack size.
Why fedora doesn't use a larger stack size :confused: ? It would save me a lot of time, and I'm sure I'm not the only one who has this problem.
I had to download a 16 stack size kernel version from linuxant, and it freezes at startup sometimes :( . If you (fedora kernel developers) can't change the fedora kernel stack size, please, tell me why and tell me how to compile a fedora kernel with a different stack size!
Tks

I think that kernel 2.6 uses an 8k stack. Are you on FC1?

by the way, the developers do not view these forum AFAIK. if you wan to tell or ask them something, you will have to file a bug report at the fedora bugzilla (http://bugzilla.redhat.com/bugzilla).

FC2 does use a 4k stack size, I remember this as the nvidia driver didn't like the 4k stacks initially. 4k stacks apparently gives about a 5% performance boost in some situations with the downside being some drivers (mostly the binary only ones) don't work.
