http://bugzilla.suse.com/show_bug.cgi?id=1167561 http://bugzilla.suse.com/show_bug.cgi?id=1167561#c1 --- Comment #1 from Steffen Winterfeldt <snwint@suse.com> --- Here's the orignal bugreport via email:
I have found that versions of hwinfo later than 21.58 crash on my machine unless I patch them. The crash (segmentation fault) occurs whenever the pci bus is scanned. Requests like --cpu and --bios go through normally.
I am running Slackware 14.2 on a Lenovo E50-00 Thinkcentre. The kernel is 4.4.199. I have traced the problem to one of the libhd source files, pci.c. Version 21.59 introduces a new PROGRESS call for hd_read_visorbus. If this is commented out, the program works. I then tried version 21.67 (which is where I first noticed the problem) and found that I needed to comment out another new PROGRESS, hd_read_mdio.
Obviously, that's a cludgy solution. There must be some code in both these functions that my hardware does not like and that could be adjusted, but I don't know enough C (or enough about hardware) to identify it.
Today I booted with the Slackware-current kernel 5.4.25, and can confirm the same behaviour, so it is unlikely to be a kernel bug.
If you would like any further information or there are any tests that you would like me to carry out, please let me know.
