Hi! I have Compaq DeskPro P450 with additional NCR SCSI controller. In 5.1-RELEASE, when I insert my USB stick I got this: uhci0: <Intel 82371AB/EB (PIIX4) USB controller> port 0x1880-0x189f irq 11 at device 20.2 on pci0 usb0: <Intel 82371AB/EB (PIIX4) USB controller> on uhci0 usb0: USB revision 1.0 uhub0: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1 uhub0: 2 ports with 2 removable, self powered umass0: vendor 0x0c76 TS128MJFLASHA, rev 1.10/1.00, addr 2 da6 at umass-sim0 bus 0 target 0 lun 0 da6: < TS128MJFLASHA 1.00> Removable Direct Access SCSI-2 device da6: 1.000MB/s transfers da6: 123MB (253400 512 byte sectors: 64H 32S/T 123C) (da6:umass-sim0:0:0:0): READ(6)/WRITE(6) not supported, increasing minimum_cmd_size to 10. umass0: at uhub0 port 1 (addr 2) disconnected (da6:umass-sim0:0:0:0): lost device (da6:umass-sim0:0:0:0): removing device entry umass0: detached And all works fine. When I insert the same USB device in 4.9PRERELEASE (cvsup at 11:00 MSD, Sep 26) I got continuous kernel panik with something like this: Fatal trap 12, page fault in kernel... Because there is no serial console I can not write hole message. I cannot make core dump - during 20-30 second I repetedly (with 1secs interval) got the same message after all comuter silently reboots... here is from /var/log/message: Sep 26 12:06:50 dru /kernel: umass0: TS128MJFLASHA, rev 1.10/1.00, addr 2 Sep 26 12:09:49 dru /kernel: Copyright (c) 1992-2003 The FreeBSD Project.
