(1394 SBP2)Rescanning SCSI bus with attached IEEE-1394 devices yields oops in kernel 2.4.20-18.9
Last modified: 2007-04-18 12:54:40 EDT
Description of problem: When running the "firewire_rescan-scsi-bus.sh"-script with attached IEEE-1394 devices, the kernel oopses. Version-Release number of selected component (if applicable): kernel 2.4.20-18.9 How reproducible: Always Steps to Reproduce: 1. attach IEEE-1394 device(s) (external harddisk & Sony DRU-500A DVD+-RW) 2. ./firewire_rescan-scsi-bus.sh , to map IEEE1394 to virtual SCSI devices 3. Actual results: oops Expected results: IEEE1394 devices should be mapped to /dev/sda, /dev/sdb, ... Additional info: This worked well with kernel 2.4.20-13.9, and hence is a regression. Could this bug be a related to bug #92193 (which does not mention an oops) ? Concerning the attached lsmod : kernel is tainted due to VMware modules.

Related to bug #97001 ?
I replaced the 2.4.20-18.9 ieee1394 driver source tree with the tarball from ieee1394-CVS (2.4 branch : http://www.linux1394.org/viewcvs/ieee1394/branches/linux-2.4/ ), which I believe is incorporated in the 2.4.21-rc series. Compilation with this script : # --- start cd /usr/src/linux-2.4 make mrproper cp configs/kernel-2.4.20-i686.config .config vi .config make oldconfig vi Makefile make dep make modules SUBDIRS="drivers/ieee1394" rm -f /lib/modules/2.4.20-18.9/kernel/drivers/ieee1394/* cp drivers/ieee1394/*.o /lib/modules/2.4.20-18.9/kernel/drivers/ieee1394 chmod 0644 /lib/modules/2.4.20-18.9/kernel/drivers/ieee1394/* depmod -a # --- stop Compilation runs flawlessly ; unfortunately, 'depmod -a' yields unresolved symbols in hosts.o , and 'modprobe ohci1394' yields an error about circular dependencies.
As discussed in thread http://lists.insecure.org/lists/linux-kernel/2003/Jul/1833.html ?
Upgraded to 2.6.1 ; WFM.
