Public bug reported: I downloaded the Intrepid Alternate Install CD daily image (2008-09-01) and I booted a machine to perform a clean install after re-partitioning the disks and doing some testing/experimenting.
Unusual things happened when I unloaded the module sd-mod (modprobe -r sd-mod): the disks powered down -- but I guess this was ok. Then, when I reloaded the module (modprobe sd-mod), I got some oopses and a kernel panic. The bug was reproducible after a reboot, and I saved the syslog. Steps to reproduce: * Boot from the Intrepid Alternate Install CD * At partman's stage, Go Back and then switch to a console/open a shell * modprobe -v -r sd-mod: rmmod /lib/modules/2.6.27-2-generic/kernel/drivers/scsi/sd_mod.ko rmmod /lib/modules/2.6.27-2-generic/kernel/lib/crc-t10dif.ko The usual noise made by the disk(s) powering down will be heard. * modprobe -v sd-mod insmod /lib/modules/2.6.27-2-generic/kernel/lib/crc-t10dif.ko insmod /lib/modules/2.6.27-2-generic/kernel/drivers/scsi/sd_mod.ko The kernel will print "kobject (f736d29c): tried to init an initialized object, something is seriously wrong." and a stack trace. Possibly, it will produce an oops and panic. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: kernel-oops linux-2.6.27 panic -- kobject: tried to init an uninitialized object when removing and re-inserting sd-mod https://bugs.launchpad.net/bugs/263746 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
