Novatel Merlin
I'm trying to get a Novatel Merlin for Ricochet working under -CURRENT. http://www.novatelwireless.com/support/support_ricochet.html I've been able to connect to their network via PPP and do things like ping and traceroute to the rest of the internet. However, when I try things that produce larger packets (ftp, telnet, ssh, etc), nothing works. I've noticed (in the PPP logs and when sending AT commands directly) that characters get dropped occasionally. I also found this document http://homepages.nyu.edu/~gmp216/nrm6842/bigfastuart.html which explains that the Merlin for Ricochet has a 576 byte buffer which, if full, will try and flush itself on a single interrupt. Apparently under linux this is a problem because the serial buffer is only 512 bytes and it overflows. Is this also a problem in FreeBSD? I also get a lot of messages like this in /var/log/messages and on the console: Jun 16 23:31:16 foo kernel: sio4: 137 more interrupt-level buffer overflows (total 821) That would seem to indicate that dumping 576 bytes on a single interrupt is too much. yes? no? If the serial buffer is too small, would it be difficult to increase it's size? Any help would be greatly appreciated. If I need to provide more info just let me know what to provide.

Re: kern/43345: Support for the SiS 651 ATA controller
I have the same hardware from shuttle and tried using the same patch on -STABLE. I found that while the patch would let the machine boot and at least use the drive at ATA100 speeds, the system was unstable. During periods of heavy disk usage there were random errors reading from the disk. I opted to keep DMA disabled and wait for Soeren's update. -Glenn At 09:24 AM 2/12/2003, you wrote: Hi, When I attempted to install FreeBSD 5.0-RELEASE on a Shuttle SS51G box, just like some other users, I encountered the "ata0: READ command timeout" error during boot. I then tried 4.7-RELEASE and saw the same problem. A quick search of the FreeBSD mail archives turned up other users with my same hardware (which uses the SiS 651 ata controller) who had encountered this. Those messages told me that I needed to either disable UDMA in my system's BIOS, or set the sysctl variable hw.ata.ata_dma to zero. I disabled UDMA in my BIOS and was able to complete the install. Then on one of the messages, I noticed a link to Patrick Bihan-Faou's problem report, read it, and tried out his patch under 5.0-CURRENT (having completed my install of 5.0-RELEASE and updated to -CURRENT). Of course the line numbers were a bit different, but a hand patch of the two files was quick and easy. A quick kernel recompile, BIOS re-enable of UDMA, and boot proved the patch worked! Thank you, Patrick, for your patch! Now for a few questions: Is there any way Patrick's solution could be temporarily committed to -CURRENT and/or -STABLE until Soeren's forthcoming real solution is available (the one Soeren mentions in the PR)? Is there some bad side effect to Patrick's two-line temporary fix that I should worry about? If there are no negatives to the patch (other than a better fix is coming in the future), is there some other reason that the patch is not a good temporary solution for users with SiS 651 based systems, so they can install and boot to FreeBSD without the work-arounds (BIOS or sysctl setting change)? Thanks for your good work, Soeren, and thanks again for your patch, Patrick. Aaron out. P.S.
