Strange cdc-acm behaviour

Hi,

Since I upgraded to 2.6.1-rc1-ben1 (BenH tree), modem hangups using USB phone (cdc-acm) cause ohci-hcd to disable itself:

# killall -HUP pppd && tail /var/log/syslog
Jan  2 09:39:02 [pppd] Hangup (SIGHUP) 
Jan  2 09:39:02 [pppd] Connection terminated. 
Jan  2 09:39:02 [pppd] Connect time 0.5 minutes. 
Jan  2 09:39:02 [pppd] Sent 283 bytes, received 273 bytes. 
Jan  2 09:39:03 [kernel] ohci_hcd 0001:01:1b.0: OHCI Unrecoverable Error, 
disabled 
Jan  2 09:39:03 [pppd]Exit.

I built ohci-hcd as a module to be able to re-use USB devices without rebooting (using rmmod && modprobe).
It didn't do that with the last version I had, which was 2.6.0-test11-benh.

Happy new year to everyone,

Colin
