Hello list,
I recently switched my debian install over from 2.4.19 to 2.4.20. Since then
I've been having trouble syncing my Palm m500 over Irda. It works, but the
transfers seem to stall a lot, making the total hotsync take over 5 minutes
to complete.
The irda transfers work fine in 2.4.19.
These are the messages in the dmesg:
ircomm_tty_attach_cable()
ircomm_tty_ias_register()
irlap_state_ndm(), media busy!
irlap_change_speed(), setting speed to 115200
irlmp_state_dtr(), Unknown event LM_LAP_CONNECT_CONFIRM
ircomm_param_service_type(), services in common=04
ircomm_param_service_type(), resulting service type=0x04
ircomm_param_xon_xoff(), XON/XOFF = 0x11,0x13
ircomm_param_enq_ack(), ENQ/ACK = 0x13,0x11
ircomm_tty_check_modem_status()
ircomm_param_xon_xoff(), XON/XOFF = 0x11,0x13
ircomm_param_enq_ack(), ENQ/ACK = 0x13,0x11
ircomm_tty_check_modem_status()
irlmp_state_dtr(), Unknown event LM_WATCHDOG_TIMEOUT
Framing or parity error!

... lots of framing errors
<here the transfer stalls and JPilot hangs>
after half a minute the transfer continues, only to stall later again.
I'm using the following irda related modules:
irtty irport ircomm-tty ircomm irda
Any ideas?
Thanks!

The IrDA patch that went into 2.4.20 have been on my web page
for over a year, so well tested...

This clearly point out to problems with the lower layer,
either the serial port or the TTY layer, not the IrDA stack. Verify
that the IrDA link is aligned and that there is no source of noise.
By any chance, are you running a preemptible or SMP kernel ?

You need to know if you are using irtty or irport.

Do :

And send the result to the serial port author/mailing list. If
you see lot's of FE, that's your problem.
Do an irdadump (with version 15 of irda-tools) while
connecting and send it the the IrDA mailing list.
Try 2.4.21-pre3.
With 2.4.20, revert the patch on my page called "Very
important fixes" and try again. If this fix the problem, you need to
try 2.4.21-pre3 with the patch called "Handle invalid QoS parameter"
and set max_tx_window to 1.

Jean
