kernel BUG at drivers/usb/storage/usb.c:848

[Markus Schaber]

Hello,

Running Kernel 2.6.4-mm2 (We use an mm2 kernel because of problems with
highmem and cryto-loop playing together which seemed to be solved in
mm2) and dd'ing from a IDE disk in an external USB case, the following
just happened (from /var/log/syslog):

The symptoms are that "ps aux" shows all processes trying to access the
disk (including the dd command) in D+ state, and the kernel does not
recognize that I removed and re-plugged USB devices in this slot. (I did
not test unplugging the other of the two USB slots I have because that's
my mouse :-)

Is this a known issue that is solved in later kernels?

Thanks,
Markus

2.6.4-mm2 is quite an old kernel.  Care to get a newer one to see if
this is still an issue or not?

It's quite some effort to update those specific machines, but we planned
to update to 2.6.7 until we heared that there are some problems with
this version (especially, a co-worker of mine trying 2.6.7-mm1 on a
similar hardware and using both crypto-loop and highmem has had random
crashes, and some apps (including sun jdk 1.4) segfaulting on startup.).

Now we plan to update to some 2.6.6 version. Is dm-crypt considered
stable enough to give it a test shot? This way, we could get rid of
crypto-loop and thus avoid having to try the mm patches.


Thanks,
Markus
