Subject2.6.0 yenta_socket eats kernel time on Toshiba Laptop
From
Hi all. First post to the list after lurking for a while; berate me if I'm
doing something wrong. ;)
I searched the archives but didn't find anything on this topic.

I've got a Toshiba Satellite Pro 4300 (PIII-750 on an Intel 440BX
chipset). Modprobing yenta_socket under 2.6.0 (I've tried test6 to test9
inclusive) causes the system to appear to lock up.
Once I managed to change consoles and run top (each keystroke took a good
20 seconds to echo), which showed that the kernel was using 100% CPU time.

Attepting a modprobe on any of the other PCMCIA bus drivers gives a
'device not found' error.

Under 2.4, the PCMCIA bus uses the i82365 module, which works perfectly.
Under 2.6, it appears that the related driver has been moved to the
yenta_socket module (It's a ToPIC100 Controller; see dmesg below).

Has anyone else with a ToPIC controller seen this behaviour?

Thanks,
Ben Hoskings <ben@jeeves.bpa.nu>
