Actually - it requires Google Drive but you can sign up for free.

@oshunluvr:

user@user-office-desktop:~$ ls -lhS /var/log
total 21G
-rw-r----- 1 syslog adm  9.9G Mar 24 07:38 kern.log.1
-rw-r----- 1 syslog adm  5.1G Mar 26 12:03 kern.log
-rw-r----- 1 syslog adm  4.8G Mar 25 07:38 syslog.1

can I just delete those log files? Will they regenerate?

Yes. The three above are the 'hogs', consuming 19.8G of space! All these logs can be deleted, and they will be recreated. Why they are as large as they are, I don't know. They are way bigger than they should be.

I would at least start reading them first.

Somewhat late, I would second this. I suggest less /var/log/kern.log, press G, and maybe page back a few pages and see what's there; it might be very repetitive. If you do want to send some log files somewhere, their repetitiveness can allow significant compression, I'd expect at least a 90% reduction.

Your log is almost entirely a kernel error regarding a wireless card. Please post your system hardware details.

ehci_hcd 0000:00:04.1: PCI-DMA: Out of IOMMU space for XXXXX bytes

[oshunluvr]

The device list from lspci should suffice. We're looking for devices at:

0000:00:04:1
0000:01:07:0

Toward the end, they seemed to have gone away. Could be an update fixed this. My opinion: delete the log files and check back in on them every day for awhile. If the above error doesn't return - you're probably OK.

I recognize that error, although I haven't personally been the victim of it. It's a new kernel issue, apparently resolved with 3.8.4. If your google translator can translate German, there's more here.

I had a similar problem to this some time back caused by my old TV card malfunctioning. The log files ballooned in size alarmingly with repetitive lines that indicated the fault was with the TV card. I knew there was something amiss at the time it was happening because the system became so unresponsive.

Simply reseating the TV card in its slot sorted the problem.
