It can be either loaded as KLD or compiled into kernel options LIBMCHAIN #mbuf management library # Kernel side iconv library options LIBICONV options SMBFS Plug a Microsoft USB mouse in and try to mount an SMB share after the USB mouse has detected. This will return a "no buffer space available" message. All other networking functions are unimpaired. Tested this with all but umass compiled directly into the kernel, and no modules. I will be able to do further tests on monday, e.g. does an existing share stop responding when the mouse is plugged in? Disconnecting the mouse does not solve the issue; shares remain non-mountable. Using 4.4-STABLE cvsuped to Friday, and smbfs userland version 1.4.1, from ports, an EtherExpress Pro 10/100, and both Windows 98 and Windows 2000 AS servers. Let me know if there is anything more I should look for and report.
