I'm not sure if this is the correct place to followup to this, but a quick google search didn't give me a related bug database for this issue. This is in response to the patch posted in this message:
http://lists.zerezo.com/linux-usb-devel/msg20582.html (the "correct" but much slower link is: http://sourceforge.net/mailarchive/message.php?msg_name=200706041123.30113.oliver%40neukum.org ) I ran into what appears to be the same problem the original poster had on 2.6.21.5 (the original poster was using 2.6.21.3). My kernel boot messages are below. The patch solved the issue for me and for the last 20 minutes at least my USB-UIRT is working perfectly (the kernel panic was on boot), although I obviously can't attest to the long-term stabiility of the changes. I did have to manually apply the first hunk (of 8) of the patch, so I'm attaching a diff against 2.6.21.5 below, also. - Michael New Diff: --- linux-2.6.21.5/drivers/usb/serial/ftdi_sio.c.orig 2007-06-11 13:37:06.000000000 -0500 +++ linux-2.6.21.5/drivers/usb/serial/ftdi_sio.c 2007-06-29 22:22:18.000000000 -0500 @@ -271,20 +271,54 @@ static __u16 vendor = FTDI_VID;
