https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=272401 Bug ID: 272401 Summary: 32 bit sysctl KERN_PROC_VM_LAYOUT hangs unkillable on 64 bit ARM Product: Base System Version: CURRENT Hardware: arm64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: jfc@mit.edu Attachment #243288 text/plain mime type: Created attachment 243288 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=243288&action=edit sysctl hang test Run the attached program compiled in a 32 bit chroot environment on 64 bit ARM. It hangs unkillable in sysctl. It is so stuck that rebooting doesn't work because the process won't die. Tools are confused about whether the program is running or runnable. The program does not accumulate CPU time. The program runs fine as a native 64 bit application. Something in 32 to 64 bit translation must be broken. Bug reported on mailing lists by Mark Millard. The original hang was in the kern_copyin test, but sysctl was to blame. -- You are receiving this mail because: You are the assignee for the bug.home | help
