Description

Seems the same slab error can be caused by attempting to read beyond the end of a usb_storage device. Can either the SCSI or usb_storage layer perform some bounds checking? Got this today. Kernel version: 2.6.9-1.681_FC3.
My setup includes using autofs to bring the mount points in on-demand.
Unmounting is not much of an issue since this device is more or less a
permanent fixture to my computer setup.
As I've been increasingly squeezed on my local HD space, I've been
increasingly relying on this external HD to pick up areas of my filesystems
that are less important. (eg. /usr/share/doc) In addition, my music files,
documents, and projects (which bash scripts will point to and execute
environment setup scripts) are on this disk.
What this means, potentially, is that this disk is becoming needed earlier in
the boot process bringing it closer and closer to when the SCSI drivers are
being loaded into the kernel. So, it could be a bad interaction and/or
deadlock between getting a vfat/usb partition all loaded and running prior to
a mount command is issued. Since this happens to be the first vfat fs to
mount, it requires these modules: fat, vfat, nls_cp950, nls_utf8, sd_mod,
usb_storage, scsi_mod to be fully loaded and operating.
I'll also wonder, out loud if I may, if this has anything to do with #129966.
What codepages, if any, are you loading on vfat mount? When you plug in the
usb device, has your usb modules been loaded previously? Or was it the first
device?
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which may contain a fix for your problem. Please update to this new kernel, and report whether or not it fixes your problem. If you have updated to Fedora Core 4 since this bug was opened, and the problem still occurs with the latest updates for that release, please change the version field of this bug to 'fc4'. Thank you. This bug has been automatically closed as part of a mass update. It had been in NEEDINFO state since July 2005. If this bug still exists in current errata kernels, please reopen this bug. There are a large number of inactive bugs in the database, and this is the only way to purge them. Thank you. |
