/var/log/messages - there are a few instances of the segfault near the end
Could you please try with kernel-2.4.9-21 if this bug is fixed? thanks Where can I get this from? Do you mean 2.4.9-31 from 7.2 updates? I can't find a copy of 2.4.9-21 for i386/i686. For what it's worth, this had been working in 7.2 before I upgraded to the beta, with 2.4.9-31. i think it should be a bug in kernel. Just wondering since I havne't heard anything yet - do you still need me to try another kernel? If so, where can I get it? It would be useful if you installed the current Raw Hide kernel from ftp.redhat.com /pub/redhat/linux/rawhide/i386/RedHat/RPMS. It is far from production, but helps to see if it fixes the problem. The maintainer (Greg K-H) told me that he fixed some similar things around 2.4.12. BTW, DO NOT REMOVE 2.4.9-31. If Raw Hide bombs on you, you have to have a backup. Have them side by side in /boot/grub/grub.conf. I tried the Rawhide kernel (2.4.18-0.10), and that produced the same segfault error as the skipjack kernel that was installed by default (2.4.18-0.4). I also installed 2.4.9-31 from 7.2 updates, and with this kernel, there is no segmentation fault. I also tried (while running 2.4.18-0.10) to rebuild the pilot-link package from SRPMS to see if that maybe helped, and that package produced the same error. Let me know what else you want me to try, or if there's any more information I can give you. This is a known bug, sorry. It's fixed in the 2.5 tree, and there's a quick fix at: http://www.kernel.org/pub/linux/kernel/people/gregkh/usb/2.4/usb-visor_hack-2.4.18.patch But that patch will break all other usb-serial drivers. I'll make a patch that will work for all devices in a short bit. Real fix for this bug is now at: http://www.kernel.org/pub/linux/kernel/people/gregkh/usb/2.4/usb-serial_visor_fix-2.4.18.patch Pete, feel free to add this to your kernel :) It is too close for a release, and I do not have the hardware even for a sanity test. I am casting about for help from Meridian people. The fix looks good, but I have a history of botching even trivial fixes, so no bending the procedure anymore for me... The fix made beta4, /pub/redhat/linux/rawhide/...... kernel-2.4.18-0.13.src.rpm. Anyone is up for testing? I'll try that kernel out sometime this weekend after I upgrade to skipjack2 and let you know. OK, this appears to me to be fixed. As long as nobody else is having problems, it's resolved. |
