Subject: PROBLEM: 2.4.21-rcX hangs when accessing HW clock on Toshiba laptop
Date: 05 Jun 2003 00:29:46 +0200 [thread overview]
Message-ID: <1054765786.448.22.camel@roamer> (raw)
Hi, this is the first time that I post a bug relating to the Linux
kernel, so if I'm not including enough information, please tell me what
else is needed. I understand that the kernel being a critical system
element makes a lot of information be needed in order to solve bugs.
I'll try to follow the form given for bug reports:
1. Kernel 2.4.21-rcX hangs when trying to access HW clock on a Toshiba
DynaBook V4/493PMHW
2. The program hwclock and thus the /etc/init.d scripts hwclock.sh and
hwclockfirst.sh are run the computer freezes. No response from the
keyboard or mouse. The cursor keeps blinking forever after the Enter key
is pressed if 'hwclock --show' is run, for instance, or the computer
hangs when it comes to adjust the system clock from the hardware clock
while running the /etc/init.d scripts. The HW clock in 2.4.20 works
perfectly.
3. Module: Character devices ---> Enhanced Real Time Clock Support
4. Linux version 2.4.21-rc7-ac1 (root@roamer) (gcc version 2.95.4
20011002 (Debian prerelease)) -- Also happened in rc2 and rc5.
5. No Oops...
6. hwclock --show or /etc/init.d/hwclock.sh
7.1. ver_linux :
If some fields are empty or look unusual you may have an old version.
Compare to the current minimal requirements in Documentation/Changes.
