Package: linux-image-2.6.17-2-686
Version: 2.6.17-9
Severity: important
Hi,
I've seen different bugs related to serial ports and the 8250 driver but
not exactly like mine, so here you get a new report (can it be that the
driver is pretty broken in the 2.6.17 kernel? :-> ).
Anyway, even though everything seems pretty OK (modules loaded, device
files present, kernel recognizes the port), I'm not able anymore to sync
with jpilot on /dev/ttyS0 under kernel 2.6.17 (I tested it: it still works
perfectly under kernel 2.6.16-18), telling me that:
pi_bind error: /dev/ttyS0 No such device
Check your serial port and settings
Exiting with status SYNC_ERROR_BIND
I get similar errors using pilot-link tools, and each time I try to access the
serial port, I get a new "ttyS0: LSR safety check engaged!" message in
dmesg.
I set the bug to important because I will have to rollback to 2.6.16;
without ability to sync PC and Palm, I can't really work.
I put some more info below, don't hesitate to tell me if you need more.
Thanks for your help, have a nice week-end,
Eric

- ttyS2 is set quiet for use by irda-utils (which works)
- parameters of the port are correct as compared with Windows
