Date: Fri, 20 Mar 2020 21:43:01 +0100 (CET) From: stratus@...a.io To: Linux Kernel <linux-kernel@...r.kernel.org> Subject: Error messages from searching /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/resource0 /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0$ sudo ag -u something resource0 (or resource1 / 1_wc / 3) This results in ag hanging, plus a huge amount of error messages are written to syslog. Once it locked up the desktop and I had to press and hold the power button. If a log file limit is not set this can quickly fill the entire partition and then the system will not reboot after it is shut down, unless something is deleted. I found this by accident when using sudo ag -u from / to search the entire file system. It occurred with the regular distro packages, and still happens when I installed the relevant -git versions from the AUR. /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0$ ls -l etc...etc: -r--r--r-- 1 root root 4096 Mar 20 01:03 resource -rw------- 1 root root 16777216 Mar 20 01:05 resource0 -rw------- 1 root root 268435456 Mar 20 01:05 resource1 -rw------- 1 root root 268435456 Mar 20 01:05 resource1_wc -rw------- 1 root root 33554432 Mar 20 01:04 resource3 -rw------- 1 root root 128 Mar 20 01:04 resource5 -r--r--r-- 1 root root 4096 Mar 20 01:03 revision etc...
