Linux TCP impotency

2001-05-13 Thread clock
Using 2.2.19 I discovered that running two simultaneous scp's (uses up whole capacity in TCP traffic) on a 115200bps full duplex serial port nullmodem cable causes the earlier started one to survive and the later to starve. Running bcp instead of the second (which uses UDP) at 11000 bytes per seco

Hi I have a SparcStation 10 with dual SuperSparc processors (_not_ sparc64), and I am unable to compile the latest kernel from vger.samba.org CVS. Standard Linus kernels neither work, but I figure they aren't supposed to... The reason seems to be that the functions pmd_alloc_one_fast, pmd_alloc

Kernel freezes after "freeing unused kernel memory"

Hi folks, I just installed RedHat 7.1 on a dual P3-733 system with 1 GB RAM. The installation went fine, but, after rebooting, the system fails to come up. The kernel loads but then eventually halts at the "freeing unused kernel memory" message. Does anyone have any ideas on what this means

Hi, I'm using the 2.4.4-ac8 kernel and found that the pci_xircom_fn() function in drivers/char/serial.c does not return a value even though it is defined as returning int. I took a look at the other initializer functions and they all return 0 (zero) on success, so I assumed that the correct

To the best of my knowledge, dev_t number is still 16 bits with 8 most significant bits being the major number and the other 8 bits being the minor number; which of course means that minor numbers can only go up to 255. Has this limitation been some how addressed with 2.4? 256 devices per module
