Description Yaron Minsky 2000-11-01 23:02:56 UTC

For some reason, hotsyncing with a visor occasionally freezes up and times
out.  This has happened with different visors on different machines, so I
suspect it's a problem with RedHat and not the hardware.  Here's the output
of the log.  Note that the key error message is the CRC Timeout message.

Comment 1 Greg Kroah-Hartman 2000-11-14 23:02:43 UTC

I'd recommend using a more up to date Visor driver, like from the 2.4.0-testX or
2.2.18preX kernel.  The one that is shipping with RedHat 7.0 is quite old.

Comment 2 Yaron Minsky 2001-03-01 15:56:18 UTC

Kernel 2.2.17-14 seems to fix the problem.
