https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D214235 Bug ID: 214235 Summary: [bwi] loading if_bwi fails to create parent DMA tag, causes "kstack allocation failed" errors Product: Ports & Packages Version: Latest Hardware: powerpc OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: freebsd-ports-bugs@FreeBSD.org Reporter: 0x5a80@protonmail.com Description:=20 Overview: On a PowerBook G4 running FreeBSD 10.3-RELEASE, using kldload= to load the bwi module fails with "could not create parent DMA tag" and running nearly any process produces "vm_thread_new: kstack allocation failed" error= s. Loading the module at boot makes the computer lose power entirely and begin booting again.=20 Steps to Reproduce:=20 1. Build and install bwi-firmware-kmod from ports on a Powerbook G4 wit= h a BCM4306v2 network card. 2. To trigger the kstack allocation errors, kldload if_bwi. 3. To trigger the repeated booting, add if_bwi_load=3D"YES" to loader.c= onf and reboot the machine. Actual Results: After "kldload if_bwi", any application that uses a significant amount of resources will fail to work -- an easy example is to = open a sizeable number of tmux windows. If if_bwi is loaded at boot time, the machine will repeatedly switch off and begin booting again midway through t= he boot process until the related modules are disabled in OFW. Expected Results: Loading if_bwi should create a bwi0 device that can be used to establish a network connection. Build Date & Hardware: Nov 05, 2016. BCM4306 rev2 on 15" Powerbook G4 (Motorola PowerPC 7457). --=20 You are receiving this mail because: You are the assignee for the bug.=
