[Oops] 2.4.23-rc1 usb-storage ehci-hcd

[Frank Horowitz]

Using the nmi-watchdog and a serial console, I've managed to capture an
Oops (attached below). 

Config: SMP. Modularized everything relevant to USB.
Chipset: Intel E7505 (ICH4 controlling USB2)
Dual Xeon 2.4GHz, 2 Gig RAM (CONFIG_HIGHMEM4G=y)

Sure fire recipe to recreate problem:
Modprobe usb-storage with ehci-hcd already loaded. IDE drive in external
USB2 case shows up as /dev/sda. Try running "hdparm -Tt /dev/sda" and no
text comes back before lockup (about 10 seconds later or so) which
generates following oops:

ksymoops bonzo_console_log.TXT
ksymoops 2.4.9 on i686 2.4.23-rc1.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.23-rc1/ (default)
     -m /boot/System.map-2.4.23-rc1 (default)
 
Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.
