It was 9600 usually, but probably it should be 112500 now, as Vladimir wrote.
If you want, you can ensure some speed on GRUB side by parameter -s ,e.g.: serial -s 112500
serial terminal_output console serial debug=all insmod ohci insmod ehci lsI didn't get anything captured, sorry... But with the serial setup, grub seems to freeze on: disk/pata.c:274: status=0x50, error=0x0, sectors=0x0 kern/disk.c:326: Closing `ata0'.
Something changed in GRUB in the meantime, so try this for current trunk code:
serial terminal_output console serial debug=all nativedisk ls > My mistake, the adapter is not a null modem. At least these pins must be connected by null-modem cable: 3 - 2 2 - 3 5 - 5This is valid for "classic" 9pin PC connectors on both sides of cable. You can check the cable by ohmmeter if it is correct.
Additionally:There exist some important USB related patches which are not included in trunk yet - see the history of mail list and search for posts from me and Melki Christian some weeks ago.
BR, Ales
