Hello,
I am using an external USB hard drive, and i hit a bug in the reiserfs code
after the drive got disconnected by a power problem. You can see this in the
attached logs.
The disconnection of the hard drive was not done manually, it has been
offlined "spontaneously" by what seems to be a power loss. In fact, i suspect
i have bad power at home since i have had other similar problems with another
device (an usb tv tuner)
However, i already have disconnected my drive manually a few times by mistake,
and i always recovered from that by unmouting, running reiserfsck and
remounting the device.
This time, although i can consider it is a hardware problem, it would have
been nice if the kernel had also recovered from the USB problem. Instead, i
couldn't unmount the filesystem and the usb stack was stucked, leaving no
choice but to reboot...
I am using a vanilla 2.6.13 kernel
Regards,
Arnaud
ps: please cc me for any reply since i'm not subscribed
