2.6.9-rc2-mm1: kernel oops on usb unplug
From: Joachim Bremer
Date: Thu Sep 16 2004 - 16:41:58 EST
This is on a dual opteron 244 (Tyan Tiger K8W). This oops happened after unplugging
a mass storage device - actually a dvd-writer. It was connected to the onboard usb1
device (AMD Chipset). Exactly the same happens on an Tyan Thunder K8W with
2 Opteron 248 connected to an PCI card with NEC chipset. Temporary workaround:
before physical disconnect issue an "remove-single-device" to the scsi-layer.
OOPS follows
Bye
