I am taking it.
Comment 3 Pete Zaitcev 2002-03-29 17:50:09 EST
ide-tape: Maximum supported speed in KBps - 4000
ide-tape: Continuous transfer limits in blocks - 0     <===== HUH?!
ide-tape: Current speed in KBps - 755

OK, device is broken, but it's not an excuse to oops.
I'll add a check or two to plug obvious holes where
the driver trusts the device microcode to return sane data.

In CVS now, but did not quite make it into 2.4.18-0.12,
so has to wait for the next release.
Comment 6 Arjan van de Ven 2002-04-05 09:42:16 EST
Built into 2.4.18-0.13
should be in beta4
Comment 7 Jay Turner 2002-04-08 20:54:37 EDT
Fix confirmed with 2.4.18-0.13 . . . I'm able to insert the module without any
issues.
