These numbers don't look right...

unstable. _sometimes_ (often enough) the kernel doesn't boot with the
following diagnostics:
I have fixed a few places that might have caused the timeout problem.
Could you download the new code and try again? Would you also add these
debug options to your config file?
options CAMDEBUG
options CAM_DEBUG_BUS=-1
options CAM_DEBUG_TARGET=-1
options CAM_DEBUG_LUN=-1
options CAM_DEBUG_FLAGS="CAM_DEBUG_INFO|CAM_DEBUG_TRACE|CAM_DEBUG_CDB"
what is possible reason of such behaviour and what should i try to do to
make my aic/cdrom combination working?

probing,
ok, but how? :)
Add this entry to the xpt_quirk_table in cam/cam_xpt.c,
{
{ T_WORM, SIP_MEDIA_REMOVABLE, "PINNACLE", "RCD*", "*" },
CAM_QUIRK_NOLUNS, /*mintags*/0, /*maxtags*/0
},

Thanks for trying the driver out, I really appreciate your patience. Since I
don't have the hardware myself, I have to rely on your help.
Thanks

Re: luoqi's aic driver problem
i've tried new "camfied" aic driver today and failed. here is a brief report. my configuration: Chaintech 6BTM mainboard with Celeron 416A processor and 128 Mb of memory Adaptec AIC-6360 SCSI controller (port 0x340 irq 9), irq 9 is reserved for Legacy/ISA card in bios setup Pinnacle 1000 CD writer (with SCSI device ID set to 0) kernel settings: options "CD9660" options "CD9660_ROOT" options SCSI_DELAY=15000 controller scbus0 controller aic0 at isa? port 0x340 irq 9 device cd0 at aic? should be just "device cd0" results: aic controller was successfully found by the kernel, but after "Waiting 15 seconds for SCSI devices to settle" message it said the following: (probe0:aic0:0:0:0): REQUEST SENSE. CDB: 3 0 0 0 20 0 (probe0:aic0:0:0:0): UNIT ATTENTION info?:1 asc:29,0 (probe0:aic0:0:0:0): Power on, reset, or bus device reset occured (probe0:aic0:0:0:1): REQUEST SENSE.

Please try the new aic.c file, it will print out if a different command is holding up the scsi bus. after that my system just hangs. The timeout handling code is flaky, I need to understand how it should work a little better. what is possible reason of such behaviour and what should i try to do to make my aic/cdrom combination working? For now you could add a quirk entry for this drive to prevent multi-lun probing, until we figure out what went wrong. thank you in advance. sincerely, ilya naumov (at work) -lq To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
