I could not find any log for the hangs, probably because it occurs while the kernel is starting and i have to press reset, so it never gets written to a logfile. The crash happend when i hotplugged an MP3 Jukebox and tried to mount it: Apr 3 12:32:26 antsrv1 kernel: umass1: ARCHOS ARCHOS USB2.0 (P4a), rev 2.00/11.01, addr 3 Apr 3 12:32:32 antsrv1 kernel: GEOM: create disk da1 dp=0xca5f0850 Apr 3 12:32:32 antsrv1 kernel: da1 at umass-sim1 bus 1 target 0 lun 0 Apr 3 12:32:32 antsrv1 kernel: da1: <HITACHI_ DK23EA-20 00K5> Fixed Direct Access SCSI-0 device Apr 3 12:32:32 antsrv1 kernel: da1: 1.000MB/s transfers Apr 3 12:32:32 antsrv1 kernel: da1: 19077MB (39070080 512 byte sectors: 255H 63S/T 2432C) Apr 3 12:33:03 antsrv1 login: ROOT LOGIN (root) ON ttyv0 Apr 3 12:38:08 antsrv1 syslogd: kernel boot file is /boot/kernel/kernel Apr 3 12:38:08 antsrv1 kernel: panic: ehci_abort_xfer: not in process context Apr 3 12:38:08 antsrv1 kernel: cpuid = 0; Apr 3 12:38:08 antsrv1 kernel: Apr 3 12:38:08 antsrv1 kernel: syncing disks, buffers remaining... 6418 6418 6418 6418 6418 6418 6418 6418 6418 6418 6418 6418 6418 6418 6418 6418 6418 6418 6418 6418 Apr 3 12:38:08 antsrv1 kernel: giving up on 3004 buffers Apr 3 12:38:08 antsrv1 kernel: Uptime: 22h44m54s Also, i get I/O-errors and the disk is inaccessible after having worked ok for days.
