Hi Petko,

David Brownell pointed out that you are the author of this driver (rtl8150).
My laptop is crashing every time I remove the Linksys EtherFast 10/100
Compact Network Adapter (model USB100M) from the USB port.

Here's a link to the discussion thus far:
http://groups.google.com/group/linux.kernel/tree/browse_frm/thread/8c93e310c7b71242/a8a1e3edb1601906?rnum=1&q=miles+lane&_done=%2Fgroup%2Flinux.kernel%2Fbrowse_frm%2Fthread%2F8c93e310c7b71242%2Fc8a8ba47c49c39fc%3Ftvc%3D1%26q%3Dmiles+lane%26#doc_a8a1e3edb1601906

Here's the stacktrace:
http://www.zip.com.au/~akpm/linux/patches/stuff/00003.jpg

I have reproduced the bug with vanilla 2.6.17. I am currently working my
back through kernel versions to try to isolate the responsible patches.

2.6.15 is the first kernel earliest kernel that seems to work with Ubuntu 6.06's
implementation of hal / udev / dbus. It does set up the adapter successfully.

I was able to reproduce the crash with 2.6.15. I have attached a screenshot
of the stacktrace. It may help, since it differs quite a bit from the one for
2.6.17-mm5.

The attachment will be too large to make it onto most mailing lists. I put
a copy here: http://www.zip.com.au/~akpm/linux/patches/stuff/00005.jpg

BTW, should I join linux-usb-devel and CC that list? Also, should I take
this discussion off of LKML?

Nah, spread it around. Who knows, somoene might actually fix the bug ;)

I don't suppose it's this easy?
