I have an external dvdwriter (nec 3500a) in a 3,5" usb2 external rack. It works flawlessly : I can burn cd/dvd without any problems. But when I switch it off, or unplug it, gentoo freezes : when under kde, the programs stops responding, and after few seconds, the mouse stop moving too. There's nothing in /var/log/kernel, and I don't know what to do. I have an up to date gentoo, using 2.6.10 kernel. Reproducible: Always Steps to Reproduce: 1.switch on dvd writer 2.use it 3.switch off the dvd writer Actual Results: the system crash, nothing respond. I have to reset y computer. Expected Results: The system sould not crash :) gentoo-dev-source 2.6.10
I posted some more infos here : http://forums.gentoo.org/viewtopic.php?t=278940 And there is a similar bug there : https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=133249
Again, more infos : two patches found, but I don't know if I can apply them on gentoo-dev-source (don't even know how to do this :/) http://marc.theaimsgroup.com/?l=linux-kernel&m=109647165425442&w=2 and http://marc.theaimsgroup.com/?l=linux-usb-devel&m=109744234829347&w=2 Hope it helps !
A quick course on patching: * copy the patch to a file on your system (for those links try the download raw, save the file, and delete the email parts leaving just the patch) * cd /usr/src/linux (or the specific source tree) * cat /path/to/patch.diff | patch * make as usual For future note if the patch includes the source tree in the file locations (ie linux-2.6.10/drivers/somefile) you have to use patch -p1 to strip off the first directory. This isn't needed for these patches, but for many you will. They will probably apply just fine against gentoo-dev-sources. Good luck!
If patching is too much trouble, could you please try 2.6.11-rc1 and see if the problem is fixed there?
Please reopen when you reply to comment #4

I'm using gentoo-dev-sources, and there is no 2.6.11rc. Which kernel could I try ?
development-sources-2.6.11_rc2
Ok, It works using development-sources-2.6.11_rc2 ;) ! Thanks ! What's the difference between gentoo-dev-sources and development-sources ? I did not find information in gentoo docs. This kernel seems to work nicely, but is a little bit slower at start I think.
See: http://www.gentoo.org/doc/en/gentoo-kernel.xml and: http://dev.gentoo.org/~dsd/gentoo-dev-sources/ Reopening bug as this issue still exists in 2.6.10 Greg, do you recall any patches going through your hands to fix this?
Lots of scsi and usb patches went in, one of them (or a combo of a bunch of them) probably fixed this.
I'm a ppc user and I've some trubble in compiling development-sources there's no patch for gentoo-dev-sources-2.6.9 ?
gentoo-dev-sources-2.6.11 is now in portage
