just tried settings `sysctl debug.kdb.panic = 1`. if i use this way to enter the kernel debugger my usb keyboard works. if i type "continue" however the kernel panics and the kernel debugger gets yet entered again, but without the keyboard working. i don't know how to produce backtraces since the keyboard doesn't work. the other way of entering the debugger without my keyboard working was to simple press "ctrl+ast+esc". alex Hans Petter Selasky schrieb am 2009-08-03: > On Monday 03 August 2009 20:28:56 Alexander Best wrote: > > to be sure i just updated my sources and rebuild/reinstalled the > > kernel. > > i'm now running > > FreeBSD otaku 8.0-BETA2 FreeBSD 8.0-BETA2 #2 r196050: Mon Aug 3 > > 18:54:46 > > CEST 2009 root@otaku:/usr/obj/usr/src/sys/ARUNDEL i386 > > still when i hit the panic key combo i'm unable to use my usb > > keyboard in > > the kernel debugger. > > alex > This is maybe because the CPU is in the USB stack already.
