Hi,
Since I upgraded to 2.5.37/2.5.38, my SMP computer has decided every night to hang without giving any Oops or error message. I've also found the following Oops while rebooting the same computer (and people wonder why I have serial cables between my PCs). My hope is that fixing the second problem would fix the first ;-)
1) Step to reproduce : -------------------- <There might be simpler, didn't bother to trim down> o boot o modprobe ohci-hcd o modprobe irda-usb o start the irda stack o stop the irda stack o rmmod irda-usb irda o rmmod ohci-hcd usbcore o sync o reboot
2) In the log : -------------
Stopping deferred execution scheduler: atd. Stopping kernel log daemon: klogd. Stopping system log daemon: syslogd. Stopping portmap daemon: portmap. Sending all processes the TERM signal... done. Sending all processes the KILL signal... done. Saving random seed... done. Unmounting remote filesystems... done. Deconfiguring network interfaces: done. Deactivating swap... done. Unmounting local filesystems... done. Rebooting...

4) And... --------- If you want, I can ksymoops the second oops, but I don't think it's necessary. The IrDA stack is very old fashioned and doesn't use any of the new device stuff. Only two IrDA-USB dongles on the OHCI card.
Have fun...
Jean
