https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D220437 Bug ID: 220437 Summary: system crashes and reboots while unpacking tarball to sdcard Product: Base System Version: CURRENT Hardware: i386 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: josua.mayer97@gmail.com Hi there; I am running FreeBSD-11.1-RC1 on an old Pentium3 machine with 512MB RAM. The device also has a USB-2.0 PCI expansion card where I attached a USB-3.0 sdcard reader by Transcend. Now what I am doing is mount slice 3 (MBR) on that card as /mnt, and unpack= a previously created tarball containing a custom freebsd build for arm. Tarball is about 900MB in size, and then gzipped with -9 to 300MB. I was using an SSH session to perform the unpacking, and after a while the console showed errors: root@pentium3:/mnt # tar -xpf /usr/local/samba/clearfog/freebsd-clearfog-20170702.tar.gz=20 usr/: Can't create 'usr' usr/lib/: Can't create 'usr/lib' usr/libexec/: Can't create 'usr/libexec' usr/libdata/: Can't create 'usr/libdata' ...... Once I noticed the situation, the machine was already halfway through rebooting, and the SSH client eventually realized that the session was dead. I have seen this behaviour before with FreeBSD as a guest to VirtualBox, wi= th that *same* cardreader and card attached via usb-passthrough! (But I didn't collect any data back then). So a crashdump was saved in /var/crash: -rw------- 1 root wheel 191M Jul 3 01:05 vmcore.0 https://vps.jm0.eu/box/sdcardcrash1.core https://vps.jm0.eu/box/sdcardcrash1.core.xz Let me know if you need further details. --=20 You are receiving this mail because: You are the assignee for the bug.=
