Subject: pcmcia oopses
Date: Mon, 04 Apr 2016 03:30:52 +0000	[thread overview]
Message-ID: <CAD4SBxDzgHSdQmHr2Qk--X-9_Nz5upJWQ4r7HJfSoUMrcXCfXw@mail.gmail.com> (raw)

Here are two oopses from kernel 4.0.4, 32 bits, on a PC with a pcmcia
slot that can handle both cardbux and 16-bit pcmcia cards.
As mentioned in my other thread, I commented out udev's call to
pcmcia-socket-startup so booting completes.

This first one occurs intermittently during boot before udev starts.
It is non-fatal and I can even use a pcmcia device.

The second one is also intermittent and is fatal.
The oops scrolled off the screen before two keyboard lights started flashing.
I think the driver was Qlogicfas.
I inserted a 16-bit pcmcia SCSI adapter, attached to a vintager CD-ROM drive.
The kernel recognized the drive.
I inserted a CD-R that was burned during this millennium and I guess the drive
couldn't read it, and a driver probably Qlogicfas couldn't handle the
error report.
Sorry, I only saw it once and didn't want to spend half an hour writing down the
tail end of the oops report.
