Bug 69524 – New mass storage device slow

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Polyhead 2004-10-30 11:17:03 UTC]

My Iriver ifp380T worked fine with 2.6.7x and back, 2.6.8 broke it all together, 2.6.9 restores function but is unbearably slow.  Average transfer rate is 72kb/s, before teh device was good for a sustained 300kb/s or so.  (scsi layer based mass storage driver).  One thing to note is that cpu0 (on my hyper thread p4 system) goes into a halt state while cpu1 remains free of load.  I've treid a kernel less smp support and no change.  Board uses an intel ICH5 chipset with an I865 northbridge.  All usb ports cause the same issue.

Reproducible: Always
Steps to Reproduce:
1.connect USB Mass Storage device
2.let hot plug pick it up
3.mount it
4. put some new files on it
5. wait 2 hours for it to unmount!

Actual Results:  
The files get there, but It takes HOURS (where before it took just a few minutes
to transfer 128mb)

Expected Results:  
Copy the files and not take all damn morning.

Anything odd appearing in dmesg? Are you sure you aren't using the ub (usb block) driver? Have you tried development-sources-2.6.10-rc1?
