did something drastically change with the 532 with regard to how usb devices are hanndled?

[Jeff Spaleta]

I'm getting TONS of I/O errors in /var/log/messages using 
kernel-2.6.8-1.532smp
when trying to plug in usb mass-storage devices.
At boot up I see this, probably from my usb flash card reader:

Aug 28 13:22:31 goober kernel: uba: device 5 capacity nsec 50 bsize 512
Aug 28 13:22:31 goober kernel: uba: made changed
Aug 28 13:22:31 goober kernel: uba: device 5 capacity nsec 50 bsize 512
Aug 28 13:22:31 goober kernel: uba: device 5 capacity nsec 50 bsize 512
Aug 28 13:22:31 goober kernel:  uba:end_request: I/O error, dev uba, sector 0
Aug 28 13:22:31 goober kernel: Buffer I/O error on device uba, logical block 0
Aug 28 13:22:31 goober kernel: end_request: I/O error, dev uba, sector 2
etc.....


when i plug in my usbdrive after boot up i see this:
Aug 28 13:26:39 goober kernel: ubb: device 6 capacity nsec 50 bsize 512
Aug 28 13:26:39 goober kernel: ubb: made changed
Aug 28 13:26:39 goober kernel: ubb: device 6 capacity nsec 50 bsize 512
Aug 28 13:26:39 goober kernel: ubb: device 6 capacity nsec 50 bsize 512
Aug 28 13:26:39 goober kernel:  ubb:end_request: I/O error, dev ubb, sector 0
Aug 28 13:26:39 goober kernel: Buffer I/O error on device ubb, logical block 0
Aug 28 13:26:39 goober kernel: end_request: I/O error, dev ubb, sector 2

and the red led on my usb keydrive is going NUTS.


I take it this is a "feature" of ub. Just when i thought I was going
to get all my hotplug issues worked out... BAM... ub decides to sneak
up on me and stabs me in the back.
Before I file this... is anyone else seeing a firehose of I/O in their
logs from ub?


I downgraded to the 526smp and things are as expected... in fact the
lasted rawhide updates
gives me back my floppy and cd drive mount points... in /media

-jef"wonders whats going to break now that his cd drive is showing up
as /media/cdrw instead of /mnt/cdrom, time to check all those silly cd
audio apps that use to expect /dev/cdrom and /mnt/cdrom"spaleta
