I upgraded to 2.4.20-gentoo-r9 after GLSA: kernel (200312-02) using genkernel. After recompiling-installing the kernel, it boots fine, but when running lsusb or plugging in a device, the system hangs with only this message in the log: [kernel] invalid operand: 0000 I also tried the compile by copying /etc/kernels/config-2.4.20-gentoo-r8 to -r9, to make sure everyting was configured identical. Re-emerging gentoo-sources doesn't help Reproducible: Always Steps to Reproduce: 1. genkernel 2. lilo 3. reboot Actual Results: Everything seems OK, but USB does not work (crash). The light on an USB Storage stick does not even turn on.

I have a similar setup (processor/compiler/cflags) and the usb stuff (stick,scanner) works fine here with -r9.
I tried xfs-sources-2.4.20-r4 and gentoo-sources-2.4.22-r1, and they both have USB working on my system (I tried to keep the config as much as possible the same). Unfortunately, XFS sources does not seem to have low-latency patch, and for some reason, 2.4.22 is unbearably slow on reiserfs internal tree checks (5-10 times slower than 2.4.20). So, I reverted to 2.4.20-r8 again, but now I know that it is not a problem with how I configured the kernel.
Can you please do the following if you are experiencing problems with -r9 and not -r8: ! Save your .config's! - Run "make mrproper" in both -r8 and -r9 trees. * Ensure that there is no difference between the trees other than the do_brk fix [ Run "diff -ur linux-2.4.20-gentoo-r8 linux-2.4.20-gentoo-r9" ] - Try recompiling linux-2.4.20-gentoo-r9 with your config.
It still crashes (only got Dec 9 11:08:50 [kernel] Unable to handle kernel paging request at virtual address fffffcdc) in the logs before everything froze >! Save your .config's! Do I need to do this, even when using genkernel? I thought I just had to copy the files in /etc/kernels?

This is very strange! I have rm -rf'd /usr/src/2.4.20-gentoo-r9 and re-emerged it before, this diffs stays...
It looks like something has possibily patched your r8 kernel sources. As a test, I would backup the 2.4.20-gentoo-r8 source, remove the current r8 source and re-emerge 2.4.20-gentoo-r8 using: 'emerge -v =sys-kernel/gentoo-sources-2.4.20-r8' Run make mrproper in the new source tree and then run the diff. At that point the diff should really only contain the Makefile. If that is the case, copy the current r8 kernel/initrd/System.map in /boot and update grub/lilo to have an entry for the backed up version and use genkernel to create a new r8 kernel and see if it has the same problems as the r9 kernel. If it does, then we know that something modified your copy of the r8 source and that your system doesn't like the gentoo-sources for some reason. Finally as a safety precaution, before starting all of the above make a complete backup of /boot and /usr/src so you can restore back to the current state if neccessary.
Guy Van Sanden: Can I please have the MD5 sums of: /var/db/pkg/sys-kernel/gentoo-sources-2.4.20-r8/gentoo-sources-2.4.20-r8.ebuild /var/db/pkg/sys-kernel/gentoo-sources-2.4.20-r9/gentoo-sources-2.4.20-r9.ebuild The only differences you should have in your trees are those Paul Varner reported in comment #6.

Guy Van Sanden: Strange - I can't trace 73e93003f3d428f0211e324428a73032 to anything which is and was in CVS for -r8. Can you please attach that ebuild?
Created attachment 22323 [details] r8 Ebuild This is my -r8 ebuild file
Hmm. For some reason the WebCVS snapshot didn't conincide with that on my end - the ebuild looks fine and the patch is correct, as the netfilter change was added later so the patch you're getting is fine. What's strange is why -r9 gives you USB problems: none of the USB code has been modified at all: the only differences between the two trees are the do_brk patch and the netfilter change. Can you please capture that OOPS message [ you should see lots of hexadecimal code which represents a stack trace; that's what we need ] and attach it here along with your .config for -r9. Thanks.
Created attachment 22337 [details] Stack dump I got this stack-dump when inserting a USB stick Doing lsusb (with or without the stick inserted) gives a kernel panic, so I'm unable to save those messages
Created attachment 22339 [details] r9 .config file This is my r9 .config, I used genkernel however, so I'm also uploading /etc/kernels/config-2.4.20-gentoo-r9 (which was used)
Created attachment 22340 [details] r9 genkernel config file
Guy Van Sanden: Can you please emerge ksymoops and do "ksymoops < file_with_output > file_with_out" on the faulty kernel and paste the output here please?
tried 2.4.20-r10, same problem. Something is odd though, if I plug a device in before boot (USB stick), and I do cdrecord --scanbus, the device is shown. lsusb crashes though.
-r10 has no changes other than the security fix so you will and should get this. I'm hoping to fix this and add a bunch of other stuff in -r11. Can I please have that stack trace?
Created attachment 23929 [details] Ksymoops output on error Requested by plasmaroo, will this one do? BTW, I'm still on a vulnerable kernel (-r8), since the 2.4.22 kernels give me NFS problems (USB works though)
Thanks, that's what I wanted - can you please enable CONFIG_USB_DEBUG and see if anything comes out from dmesg?
CONFIG_USB_DEBUG set, but no more information is logged
Have you tried upgrading to one of the later 2.4, or even a 2,6, kernel? Does the issue still exist?
This bug has gone stale. Three months without hearing anything. Marking fixed unless I hear other wise.
