Hello: I have been getting reproducable panics with most CDROM related actions including mounting CDROMs and playing audio CDs. IIRC, this has been happening since the statfs changes a week earlier. Can provide more information if required. Kernel has been compiled with "device atapicam". I am rebuilding the kernel w/o "atapicam" ATM. Thank you for your time. -- Shanu http://shankerbalan.com/ [godzilla] ~> uname -a FreeBSD godzilla.exocore.com 5.2-BETA FreeBSD 5.2-BETA #0: Tue Nov 25 15:34:37 IST 2003 root@godzilla.exocore.com:/usr/obj/usr/src/sys/MYKERNEL i386 [godzilla] ~> dmesg | egrep -i 'geom|cd0' GEOM: create disk ad0 dp=3D0xc2da0360 GEOM: create disk ad2 dp=3D0xc2d9fe60 acd0: CDROM <SAMSUNG CD-ROM SC-152C> at ata1-slave PIO4 GEOM: create disk cd0 dp=3D0xc2d8ce00 cd0 at ata1 bus 0 target 1 lun 0 cd0: <SAMSUNG CD-ROM SC-152C CS05> Removable CD-ROM SCSI-0 device=20 cd0: 16.000MB/s transfers cd0: Attempt to query device size failed: NOT READY, Medium not present [godzilla] ~> sudo gdb -k /usr/obj/usr/src/sys/MYKERNEL/kernel.debug /usr/c= rash/vmcore.0 GNU gdb 5.2.1 (FreeBSD) Copyright 2002 Free Software Foundation, Inc.
